Bug Description

Thunderbird freezes at random. I must kill it then reload it.
Sometimes the freeze happens when sending a mail. I had no problem in 11.10.

It happens several times a day. The only pattern that I can currently see is that the freeze happens frequently when thunderbird is using the network.

[Test Case]
* Install update
* Run Firefox/Thunderbird for a day
* Make sure it does not freeze

[Regression Potential]
* Minimal
* Upstream release for gtk2-engines-oxygen is only a bug fix release

I'm seeing this frequently on both a desktop and a laptop running Kubuntu 13.04 (Alpha 1) with KDE 4.10.00. Thunderbird version is currently 17.0.2.

This seems to happen after leaving Thunderbird running in the background for several hours checking mail but not otherwise using the program. Whether the freeze occurs when Thunderbird is checking mail I can't say but the freeze has happened frequently enough for me to search for and add to existing bug reports.

Udo Schuermann (udo-schuermann) wrote :

I've noticed today that Dolphin refused to open a window for folders when I double clicked on the desktop icons. It just sat there, and sure enough both Firefox and Thunderbird were both frozen dead. As soon as I killed FF and TB, another double click on the folder icons responded instantly.

Might there be a lock (or lock process) involved that hangs and affects more than just FF and TB?

That said, I've seen Firefox and Thunderbird hang independently of the other (one was fine while the other was hung), but I find the observed behavior worth mentioning.

(Kubuntu Raring Ringtail, amd64, nvidia 310 (experimental) driver)

Paul White (paulw2u) wrote :

I'm seeing this problem a lot less now.

KDE is now at version 4.10.1, Firefox 19.0.2 and Thunderbird 17.0.4 but both Firefox and Thunderbird seem to freeze at the same time. No other applications seem to be affected here.

I'm also experiencing issue described by Paul White - both Firefox and Thunderbird freeze at the same time, no other application is affected. I'm also on Kubuntu Raring.

Mikael Gerdin (mgerdin) wrote :

I believe this is actually a bug in the Oxygen GTK engine.
Attached is some gdb output I took from a hung thunderbird.

It looks like Oxygen-gtk2 is spawning a new glib main loop when it's running "kde4-config --path config"

While writing this exact comment I got the exact same hang in Firefox.

Mikael Gerdin (mgerdin) wrote :

I just found 1142213, which looks like the issue that I saw in the GDB output.
This bug may or may not be a duplicate of 1142213 but the freezes I've experienced are most ceratainly due to 1142213.

David J. Wallace (katana-p) wrote :

I'm affected by this. Fresh installation of Kubuntu 13.04 64 bit. Thunderbird and FIrefox randomly hang, often after an idle period. Have tried changing theme to see if the oxygen-gtk theme may be the issue as suggested. This would seem to have solved the issue.

May be unrelated, but if thunderbird or firefox is launched from the command line they throw a critical glibc error:

(process:3400): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

New to this - what can I do to help?

Mark (mapk) wrote :

Same for me, everything ran great until I upgrade to Raring from 12.x

Firefox 20.0, Thunderbird 17.0.5

The only thing I recall about upgrading is that new nVidia drivers were install during the upgrade.

I was not using Oxygen GTK theme, I was using the Air Black Remix for Window Decorations and Glassified for desktop theme.

Switched both anyway to see if that helps.

Mark (mapk) wrote :

I've switch themes a few times - still happening regardless of desktop theme.

Larry Tate (cathect) wrote :

I can confirm David Wallace's assertion that this seems to happen after the computer wakes from idle.

The first email I try to send at that point freezes my machine for approximately 1.5 minutes. Then the email goes through and my system is back. It seems that it is actually going through the window animation in extreme slow motion...

Ian Brock (brock-physik) wrote :

I see the same effect with Kubuntu 13.04 64 bit. Clean install.
Thundrbird 17.0.5
Firefox 20.0
Desktop theme is Oxygen

The hang also seems to happen when Thunderbird and Firefox have been idle for a while. I do not see any such problems with other applications.

Mark (mapk) wrote :

Ok more tests. With the Oxygen theme I get the lockups. When I switch GTK-2 to Raleigh and GTK-3 to Emacs the lockups go away. But I'm stuck using themes that are, uh, just a bit too 1990's for my tastes - LOL.

Paul White (paulw2u) wrote :

I'm removing the duplicate status of this bug.

This bug is about Firefox and Thunderbird freezing after starting successfully.

Bug #1142213 is about GTK applications including Emacs not starting at all for which as fix has been found

Petr Sedlacek (petr-sedlacek) wrote :

FWIW, I haven't seen one of these freezes since I switched gtk2 theme from oxygen-gtk to Oxygen-Molecule-Flat. Normally I would experience at least one freeze every two days (usually more often).

I have now patched gtk2-engines-oxygen 1.3.3 with the changes mentioned in the Emacs bug report: - the changes don't seem to be relevant to the issue we are experiencing here but let's see if the newest version of gtk2-engines-oxygen helps.

Rogi (rogi) wrote :

I can always reproduce this problem with taking a screen shot of Firefox (maximized) in Kubuntu (default KSnapshot) and after saving Firefox hangs. Switching to Raleigh and Emacs GTK themes solves this.

Mark (mapk) wrote :

I saw some Kubuntu updates come through last night one of which was related to kde-style-oxygen in some form or fashion. Installed all the available updates for Raring and this freezing issue with Firefox and Thunderbird still occurs with GTK oxygen in use. Does not happen with Chrome browser though.

Pacific Seascape (seascape) wrote :

I am affected by this as well. I use Firefox and Thunderbird extensively so this is a really serious problem. I thought I'd wait a few weeks before upgrading to Raring in the hopes that bugs like this would have been squelched. That plan worked out well...

Petr Sedlacek (petr-sedlacek) wrote :

Just an update to my comment #19 (a week ago) - I haven't experienced any of these freezes since I upgraded gtk2-engines-oxygen to version 1.3.3 with the patches mentioned in the Emacs bug report: The patches might not be relevant so it's possible that the latest upstream version fixes the freezes.

I can provide amd64 package if there's interest.

Torsten Römer (dode) wrote :

Petr, I'd be interested in your amd64 package. FF and TB both are nearly unusable, I'd be very happy for a solution!

ronwilhoite (ronwilhoite) wrote :

Thank you Petr! No freezes in Thunderbird or Firefox since installing your deb. It has only been a few hours, but I would have already had at least one in that time before the update.

Does somebody have the 1.3.3 package for 32-bit system?

Petr Sedlacek (petr-sedlacek) wrote :

Glad to hear the new version helped.

I do not have an i386 raring vm to build the deb but here is a quick guide how to do it yourself:
# install debian build tools - not sure I didn't miss any
sudo apt-get install dpkg-dev debhelper
# install build dependencies
sudo apt-get build-dep gtk2-engines-oxygen
# get the source (version 1.3.1)
apt-get source gtk2-engines-oxygen
cd gtk2-engines-oxygen-1.3.1
# update the source to 1.3.3
wget -q -O- | gzip -dc | patch -p1
# patch the source - these are the changesets from oxygen-gtk git - see
wget | patch -p1
wget | patch - p1
wget | patch -p1
# build the package
dpkg-buildpackage -b -us -uc -j2

Torsten Römer (dode) wrote :

Thanks also from me Petr, no freeze the whole day so far, while there was 5-20 each day before.

I'm glad we have a stable system again :-)

Pacific Seascape (seascape) wrote :

Just installed Petr's .deb package on my Kubuntu 13.04 installation. Wow, what a difference. Not seeing any freezes (fingers crossed!) and Thunderbird and Firefox both seem *much* more responsive - the UI slowness appears to be gone. What a relief. Thank you so much, Petr!

I built and tried 32bit version of gtk2-engines-oxygen_1.3.3 according to the Peter's instructions. Unfortunately it didn't solve the problem...

Andreas Tetzner (a-tetzner) wrote :

Petr's packages also worked for me, no freezes since installing them.

David J. Wallace (katana-p) wrote :

Yes - Petr's deb fixes the problem here. Thank you Petr.

Does somebody wants to test 32bit version of gtk2-engines-oxygen_1.3.3? It didn't fix the problem for me. I can provide the .deb for anybody who wants to test it.

Leonid: can you link the 32-bit .deb?

Thanks Leonid, for you it's still freezing?
Is only gtk2-engines-oxygen affected or also gtk3-engines-oxygen?

Gavin Sharpe (gavin77) wrote :

I've been using the patched package from comment #26 for the past 48+ hours and haven't had any crashes or lockups. It seems to have fixed it here.

Starbuck, unfortunately both Firefox and Thunderbird is still freezing on my 32bit Kubuntu. I didn't anything with gtk3-engines-oxygen. Neither Firefox nor Thunderbird use it.

5e22bbf8bf09663f2be9cd7510a956fc5ad4faba is the core of the fix. The two follow-up patches are minor improvements on it. They are not required to have this work.

Also, if all goes as planned, oxygen-gtk{2,3} with this fix is expected to be released today.
