Bug#549959: gnome-panel: Gnome-Panel 2.28 crashes with certain notification icons

[Brian Hill]

Package: gnome-panel
Version: 2.28.0-1
Severity: important

Since upgrading to gnome-panel 2.28, I've noticed the that certain programs that have notification icons will cause the panel to crash.

In particular, Transmission is causing the panel to crash when I exit the program using the icon. Also, rhythmbox will crash the panel when first opened.  After the panel restarts, rhythmbox works fine until the next time I log out and back into Gnome is which case the behaviour repeats.

Gnome-panel is outputting the following to stderr when it crashes :
(gnome-panel:25384): Gdk-CRITICAL **: gdk_x11_colormap_foreign_new: assertion `GDK_IS_VISUAL (visual)' failed
The program 'gnome-panel' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadPixmap (invalid Pixmap parameter)'.
  (Details: serial 18386 error_code 4 request_code 54 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.)
