Description Gediminas Paulauskas 2002-03-02 21:08:02 UTC 
Package: gnome-panel
Severity: critical
Version: 1.5.11
Synopsis: crashes when removing a panel
Bugzilla-Product: gnome-panel
Bugzilla-Component: Panel
BugBuddy-GnomeVersion: 2.0 (1.112.0)

Description:
This is yet another crash-on-remove bug. I have a patch from
http://bugzilla.gnome.org/show_bug.cgi?id=72167 applied, but now it
crashes elsewhere (in panel, not tasklist/pager).

I created one floating panel, added a pager to it, clicked "remove this
panel", answered "yes". repeatable.

Comment 1 Gediminas Paulauskas 2002-03-02 21:18:56 UTC 
in terminal it prints only 

woo, in the remove panel query: 0x828ecc8!

gnome-panel-2 (pid:18045): GLib-GObject-WARNING **: invalid cast from
(NULL) pointer to `PanelAppletFrame'

when in the panel there is nothing or some launchers, works OK, but if
there is any applet (tasklist or clock), it crashes.

Comment 3 Arvind S N 2002-03-07 11:55:43 UTC 
This attachment also solves the bug 72646 and bug 73325.
The panel crash when tasklist is present bug 72974 still remains.
But the crashes when other applets exist on the panel are solved with
this attachment.

I have just commited this patch, because it fixes crash for me.
I guess this bug was caused by unfinished work by George, so he would
probably change this later...
