Public bug reported:
After dist-upgrading my amd64 Intrepid workstation to Jaunty, gnome-
panel began to freeze when I launched "Custom Application Launchers".
After some restarting and investigating I determined that the problem
does not happen immediately when the Gnome session starts, but can take
several hours to manifest itself. Once the problem has manifested
itself, launching a "Custom Application Launcher" will seemingly
"freeze" gnome-panel, causing no GUI updates to be done to any of the
launchers.
I have several panels, and on any of them "Custom Application
Launchers", and ONLY Custom ones, cause the freeze.
When the freeze occurs, the opening effect which is shown when you click
a launcher (the one that shows a wireframe sort of box expanding out
from the launcher eventually sizing itself to the perimeter of the
screen and disappearing) freezes, hung on the screen at the last row of
pixels on the edges.
If I ssh in to my workstation and killall gnome-panel, gnome-panel
restarts normally, but the "freeze" still occurs when I attempt to
launch Custom Application Launchers. Applets and non-custom launchers
work normally. Restarting my X/Gnome session resolves the problem for
an hour or so until it manifests itself again.
gnome-panel :: 1:2.26.0-0ubuntu7
Ubuntu 9.04 Jaunty AMD64
I am running two 1920x1080 displays as :0.0 and :0.1, and xinerama.
I attached gdb to the frozen gnome-panel and observed the backtrace,
attached as gnome-panel-freeze-backtrace.txt
