Having just patched glib to fix bug #290935 "dual screen all panels end
up on one screen at startup" I'm using dual screens again and hit this
bug whilst using compiz cube and nvidia drivers.
Metacity "/apps/metacity/general/compositing_manager" = false.
Running gnome-panel from within gdb shows the following stack-trace when
gnome-panel crashes after clicking on a custom launcher on the gnome-
panel on screen 1. This doesn't crash using the 'standard' menu items on
screen 1. (Screen 1 is the *second* screen).
The problem seems to originate from:

[New Thread 0x7f50e1b83950 (LWP 9797)]
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 18571 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.)
Program received signal SIGPIPE, Broken pipe.
