gnome-panel / nautilus hang due to gnome-vfs-daemon

[leon breedt]

hi,

on hoary, running the latest (as of 2004-12-19) packages:

gnome-vfs2: 2.9.1-0ubuntu2
nautilus: 2.9.1-0ubuntu4
gnome-panel: 2.9.2cvs041215-0ubuntu1

causes some problems for me.

mainly, nautilus is blocked in a futex() syscall, along with gnome-panel, and
any application that tries to use a file chooser.
is it perhaps a problem in gnome-vfs2? i'm not sure what causes this at all.

i've rebooted a few times, and once, by chance, it didn't do this, but all
subsequent reboots have, so perhaps its a timing related
bug.

This is probably related to:

https://bugzilla.ubuntu.com/show_bug.cgi?id=4764

As I had those same symptoms even when it "worked" after a reboot :)

[leon breedt (bitserf+bugzilla)]

i installed the debug packages and did some tracing.

a backtrace of the hung nautilus:

seems to be related to the dbus restart:
http://bugzilla.gnome.org/show_bug.cgi?id=161997

workaround for people getting this : "killall gnome-panel gnome-vfs-daemon
nautilus trashapplet drivemount_applet2"

BTW I've uploaded a new gnome-vfs2 without hal, let me know if you still get
this bug with it.

It's still there (on amd64) after dist-upgrade. Anything I can do to help debug it?

Great works ubuntu-folk!

[Sebastien Bacher (seb128)]

have you restarted the box ?

[torb (torrb)]

Yes.

[torb (torrb)]

Since the last update to gnome-vfs I have had a hattrick of successful logins,
it seems to work.

Thanks for your time!

[leon breedt (bitserf+bugzilla)]

sorry to be the bearer of bad news, but i just had the problem again, after a
cold boot.

gnome-panel: 2.9.3-0ubuntu1
gnome-vfs2: 2.9.2-0ubuntu3

doing the "killall gnome-panel gnome-vfs-daemon nautilus trashapplet
drivemount_applet2"
fixes it.

[Sebastien Bacher (seb128)]

could you get a backtrace of the problem with the current versions ? I have no
problem since the hal support is off but getting a backtrace
could be useful, perhaps that's a different issue now

[leon breedt (bitserf+bugzilla)]

it seems to happen in the same place. here are the backtraces for

I got a similar problem too. To solve that I have removed my session
($HOME/gnome2/sesssion) and everything work fine after rebooting.

If I save the session again before leaving the desktop I fall again in the
problem ... and I have to remove my session agin ...

Don't know if it can help.

[Sebastien Bacher (seb128)]

should be fixed for hoary

[Paul Sladen (sladen)]

Workaround I successfully used with a 100% success rate to get around this is:

  sudo pkill -u $USER

and re-login when GDM provides a new login-dialogue.

[torb (torrb)]

It seems to have become more frequent the last few days.

[Ernst Persson (ernstp)]

I still see this. (AMD64)

Clearing .gnome2/session* and .gnome2/.gnome-sm* and then killing stuff seems to
help.

[Sebastien Bacher (seb128)]

does anybody here still get this issue/is able to get the lock somewhere ?

I've put a patched version of gnome-vfs2 that might fix this issue here (i386
deb and sources): http://people.ubuntu.com/~seb128/vfs/

any feedback on this would be welcome

[Sebastien Bacher (seb128)]

I've uploaded the patched version in the archive:

 gnome-vfs2 (2.9.3-0ubuntu2) hoary; urgency=low
 .
   * debian/patches/14_vfsdaemonlock.patch:
     - upstream patch to fix the gnome-panel/nautilus freeze (Hoary: #4794).

Please let me know if you get the issue after restarting and while using these
packages.

[leon breedt (bitserf+bugzilla)]

i haven't had the problem since the update (a few reboots later, which would
have caused it previously, but now doesn't).

thanks

[Sebastien Bacher (seb128)]

nice, thanks for the feedback. Seems to be fixed, I'm closing the bug. Feel free
to reopen if that happens again.

[tomekb (tomcio-bielecki)]

Still in Dapper!
After dist-upgrading from breeze yesterday my system become unusable. Gnome panel doesn't display anything except menu and does not respond to mouse clicks. Also nautilus keeps refreshing itself constantly.
Problem dissapears if I log on to newly created account.
