X protocol error: BadPixmap (invalid Pixmap parameter) on protocol request 56

[Simon Josefsson]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Gnus was getting new mail and I pressed C-g and got the following
backtrace.  The gdb process is still running if you want additional
information.
