Bug Description

Hi! I'll post same info posted on Ubuntu Forums: http://ubuntuforums.org/showthread.php?t=1219305

Recently I've updated to latest kernel 2.6.28-14-generic i686 in my Jaunty Jackalope 9.04 32-bit system.

I use kde4 4.3 RC and in the latest days I've been suffering of massive core dumping due to 'segmentation fault' my applications that depend on Gnome libs.

My thunderbird can't even save an attachment, it just cores dump

I've tried gedit from console, it cores dump even before starting!

Here is the backtrace of gdb on gedit behavior:

(gdb) bt
#0 0x00000000 in ?? ()
#1 0xb790cd9d in ?? () from /usr/lib/libgio-2.0.so.0
#2 0xb78e58b2 in ?? () from /usr/lib/libgio-2.0.so.0

#7 0xb76b04ff in start_thread () from /lib/tls/i686/cmov/libpthread.so.0

From my thunderbird launched on console:
$ /usr/lib/thunderbird/thunderbird

#0 0xb808e430 in __kernel_vsyscall ()
#1 0xb7ec74b0 in raise () from /lib/tls/i686/cmov/libpthread.so.0

#12 0xb74a749e in clone () from /lib/tls/i686/cmov/libc.so.6

As you can see something in libgio-2.0.so is wrong. Maybe some new bug due to latest kernel patch (that nasty bug on NULL pointers stuff).

Interesting part:
if open gedit with gksudo it just works witout any core dump!

$ gksudo gedit

Any help?

Thanks and regards!

More information:

Using Firefox when downloading a file (lucky me) opened the file-browser window effectively (no core dump here). The difference is is last path Firefox saved was /usr/share/icons, then I've changed to <home dir> and, here we go, crash and core dump!

Tried again but now trying to save on /tmp. Again, crash and core dump.

Here is my directory rights:

drwxr-xr-x 22 root root 4096 2009-07-17 12:38 icons

Tried also reinstalling libglib. But same behavior...

sudo aptitude reinstall libglib2.0-0

Any help? I'm really stuck on common operations with my desktop :(

Take a look at this: "\230Q�\b\002"

I also updated my system to latest KDE 4.2.98 (KDE 4.3 RC3)

Any help?

This issue still exists and it's really anoying. Can't work with firefox, thunderbird, nothing that depends on the gnome file browser.

Workaround here: http://bugzilla.gnome.org/show_bug.cgi?id=591606

I'll describe how to reproduce it on my Ubuntu 9.04 32-bit (fully updated to
latest version).

The problem is in the file '$HOME/.local/share/mime/mime.cache' (I think it's
corrupted. I've attached above this post a strace dump file and a corrupted
mime.cache file as a tar.gz directory).

Steps to reproduce it:

1) Backup your '.local/' dir

$ mv $HOME/.local/ $HOME/.local_bkp/

2) Create a NEW '.local/' dir
$ mkdir $HOME/.local/; mkdir $HOME/.local/share; mkdir $HOME/.local/share/mime/

3) Copy corrupted 'mime.cache' attached in this post to the NEW dir.
$ cp bug_591606/mime.cache $HOME/.local/share/mime/

4) Launch program linked against libgio (i.e. nautilus)
$ nautilus

5) Enjoy your Segmentation Fault ;)

Steps to workaround:

1) Move '$HOME/.local/share/mime/mime.cache' file to a temporary dir just to
backup it
$ mv $HOME/.local/share/mime/mime.cache $HOME/<temporary_dir>

2) Launch nautilus to test it
$ nautilus

That's all folks!

PD: Anyway, can anybody confirm this bug? Please!

Guys, I'm having (again) the same issue... ;_(

All my apps core's dump whenever a file explorer windows opens-up or I have to navigate to $HOME folder.

******************************************************* Package information: ******************************

Here is attached the mime.cache file which is causing this behavior. The older one (also attached in previous post was deleted once).

The only way to workaround this bug is, in fact, deleting the mime.cache file.

Again... :(

This is really annoying me....have to delete each day $HOME/.local/share/mime/mime.cache

Is there any way you help me in finding which app is corrupting '$HOME/.local/share/mime/mime.cache' file?

Thanks ;_(

Thanks, I was getting this on gentoo under kde4. I had added an icon to a mimetype and then deleted the icon to change it and that's when it started crashing. But libgio shouldn't crash like that, regardless.

I got the same problem, with the same workaround, today just after upgrading Mozilla Firefox to v18.0. I had a hard time solving the problem.

  * Anything linked to libgio-2.0 do segfault.
  * cannot login using xfce4-session or gnome-session
  * dbus not working either
  * using xinit and then opera, I could still use internet!

  rm ~/.local/share/mime/mime.cache
