thunderbird assertion errors when started in KDE-console: (thunderbird-bin): GLib-CRITICAL **: g_hash_table_insert_internal: assertion `hash_table != NULL' failed (thunderbird-bin): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

Binary package hint: thunderbird

I am logged in under a KDE session. Starting thunderbird via KDE-console/shell yields the following assertion error:

(thunderbird-bin:19460): GLib-CRITICAL **: g_hash_table_insert_internal: assertion `hash_table != NULL' failed

After closing thunderbird this assertion error appears:
(thunderbird-bin:19460): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

The application itself seems to run properly, although I'm not sure whether it's luck or determination.

This bug does seem to be related to KDE - if I do the same in an 'Ubuntu Classic'-session everything works fine and no assertion error is printed in the shell.

Hope this will help...

On KDE4.6.5 Kubuntu 11.04, I get the same error for a while now.
Just found that this happens to me if SystemSettings->AppAppearance->GTK+Appearance->Widget style = oxygen-gtk
Also, all gtk apps will start with this error but run fine.

Workaround:
SystemSettings->AppAppearance->GTK+Appearance->Widget style = QtCurve

Update:

On KDE 4.7.2 Kubuntu 11.10, I do not see this issue anymore.
SystemSettings->AppAppearance->GTK+Appearance->Widget style = oxygen-gtk
works fine.

To anyone affected by this bug,

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. This bug was reported some time ago and there have been many changes in Ubuntu and Thunderbird since that time.

Do you still see a problem related to the one that was reported in a currently supported version of Ubuntu?

Please let us know if you do otherwise this bug report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
