Public bug reported:
Ubuntu: Jaunty 9.04 64bit desktop
gnome-panel: 1:2.26.0-0ubuntu7
Yesterday I rearranged some applets and launchers on my gnome-panels,
and ever since, gnome-panel crashes over and over forever when I log in.
I can see the panels appear briefly, and then a window titled "Error"
appears in the middle of my second monitor (configured as separate X
screens), but before any content is drawn in the Error window, it all
disappears. A moment later, the panels reappear briefly, then the Error
window, then gone. Over and over.
Every time gnome-panel crashes and restarts and generates its Error
window, it steals the input focus. So even if I manage to get a
terminal window open (by clicking its launcher on one panel before they
crash), I have to keep re-clicking the terminal window and quickly
typing one letter before the next Error window comes up and steals
focus. In this way I can type out "killall gnome-panel", which stops
the cycle, but only if I'm lucky enough to do it between gnome-panel
restarting and crashing again -- if it's in between launchers, killall
finds no process and does nothing.
There is nothing in /var/crash but my ~/.xsession-errors is full of this
section, repeated hundreds of times:

The program 'gnome-panel' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 2330 error_code 8 request_code 1 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
