Description Bob Glickstein 2006-06-14 12:46:26 EDT

After upgrading to gnome-panel-2.14.2-1.fc5.1 (along with a handful of others),
gnome-panel now exits on startup with this assertion failure:

** ERROR **: file orbit-object.c: line 149 (do_unref): assertion failed:
(robj->refs < ORBIT_REFCOUNT_MAX && robj->refs > 0)

Version-Release number of selected component (if applicable):
2.14.2-1.fc5.1

How reproducible:
100%

Steps to Reproduce:
1. Launch gnome-panel
  
Actual results:
Panel gets partially populated, then posts the "unexpected quit" dialog.

Expected results:
No abrupt exit.

Additional info:
I found this relevant message in the fedora-test-list mailing-list archive:
http://www.redhat.com/archives/rhl-beta-list/2006-March/msg00170.html

Also, I captured this stack trace in gdb:

Also, here is an excerpt from my yum.log.  One of these updates, or a
combination of them, is probably the culprit.

Comment 1 Bob Glickstein 2006-06-14 13:30:02 EDT

Of the yum updates I listed, I tried reverting with the following older RPMs:

control-center-2.14.1-1.fc5.2.i386.rpm
evolution-2.6.1-1.fc5.2.i386.rpm
evolution-connector-2.6.1-1.fc5.1.i386.rpm
evolution-data-server-1.6.1-1.fc5.2.i386.rpm
evolution-sharp-0.10.2-9.i386.rpm
evolution-webcal-2.4.1-3.2.i386.rpm
glib2-2.10.2-1.fc5.1.i386.rpm
glib2-devel-2.10.2-1.fc5.1.i386.rpm
gnome-applets-2.14.1-1.fc5.1.i386.rpm
gnome-desktop-2.14.1.1-1.fc5.1.i386.rpm
gnome-games-2.14.1-1.fc5.3.i386.rpm
gnome-media-2.14.0-2.i386.rpm
gnome-panel-2.14.1-1.fc5.1.i386.rpm
gnome-panel-devel-2.14.1-1.fc5.1.i386.rpm
gnome-session-2.14.1-1.fc5.1.i386.rpm
gnome-themes-2.14.0-1.noarch.rpm
gnome-utils-2.14.0-4.fc5.1.i386.rpm
gnome-vfs2-2.14.1-1.fc5.2.i386.rpm
gnome-vfs2-devel-2.14.1-1.fc5.2.i386.rpm
gnome-vfs2-smb-2.14.1-1.fc5.2.i386.rpm
gtk2-2.8.17-1.fc5.1.i386.rpm
gtk2-devel-2.8.17-1.fc5.1.i386.rpm
libgnome-2.14.0-1.i386.rpm
libgnome-devel-2.14.0-1.i386.rpm
libgnomeui-2.14.0-1.i386.rpm
libgnomeui-devel-2.14.0-1.i386.rpm

(I also removed gnome-themes-extras altogether.)  But the bug remains, and the
RPMs that I didn't revert (such as dia, module-init-tools, etc.) strike me as
highly unlikely to be related to the bug.  So the problem must lie somewhere else...

Comment 2 Bob Glickstein 2006-06-16 14:12:00 EDT

EUREKA.  When I noticed that (according to the call stack) Bonobo was calling
ORBit with a null object, I inspected my panel configuration using gconf-editor.
 Sure enough, I found an applet -- /apps/panel/applet_3 in gconf -- with no
properties, but with some settings in /apps/panel/applet_3/prefs that made it
look like it was once something pilot-related.  I removed the
appls/panel/applets/applet_3 subtree from my $HOME/.gconf directory, then
renamed applet_4 to applet_3 just in case.  (A change that I then reflected in
apps/panel/%gconf.xml.)

After launching a new session (to get a new gconfd instance), all was well.

I presume that one of my many software updates must have left that applet config
in a bad state.  It might be worth putting some code into gnome-panel to defend
against this condition.

Comment 3 Ray Strode [halfline] 2008-03-18 14:33:31 EDT

Hi,

We no longer support Fedora Core 5 and I am currently trying to get my open bug
count down to a more manageable state.  I'm going to close this bug as WONTFIX.
 If this issue is still a concern for you, would you mind trying to reproduce on
a supported version of Fedora and reopening?

(this is a mass message)
