This is one bug. Thanks for bringing it to our attention. However,
this crash happens when a display connection is closed, which is not
common in normal use. As the backtraces you attached show, an unrelated
X error is what caused a connection to be closed.
To really fix this bug, we need to know the details of the X error.
Once you reach the breakpoint on `x_error_quitter', would you please
run:
(gdb) p *event
and send us the resulting print out?
