Thanks.

This configure event is wrong: it specifies a width and height of zero,
which are invalid under X. Then, the shell widget tries to reconfigure
its window to those invalid dimensions, which causes the crash.
The `send_event' field indicates that this event was sent by another
client and not the X server after window configuration (since we don't
send ConfigureNotify events to ourself anywhere in Emacs).
Please try to find the program that is sending these events. It could
be a badly behaved window manager, for example.
