Detected problem with gnome panel in ubuntu

[Albert Cardona-2]

Dear all,

On occasions ImageJ seems to lock up in Ubuntu 9.04 when using the Gnome
desktop.

ImageJ doesn't lock up; it's the gnome-panel application who does!

A temporary workaround to rescue ImageJ is to:

1. control+alt+F2 to a tty
2. login
3. run 'top'
4. kill the gnome-panel application, which is running at ~33% CPU
    (Xorg will list as using the other 66%)
    To do so, push 'k' and then type in the pid number of gnome-panel,
    and type 'y' plus return key to the question.

5. control+alt+F7 (or F8, or F9...) to go back to your desktop.

Back in the desktop, ImageJ then is run fine again.

If anyone figures out how to reproducibly trigger this bug, please
report it to ubuntu launchpad bug tracker. Thanks.

Albert

I think the problem might be related to metacity, as the problems stopped
on one of my computers after switching to compiz.  Unfortunately, on
another computer, the problems persist, and they are not related to ImageJ
at all, and the problems are worse, as I cannot even switch to a text
terminal.
