I solved without resorting to ssh (as that was not an option for me
here) with the following "magic" command-line:
# gdb -p $(pidof X) -batch -ex 'handle all nostop' -ex 'handle all pass'
-ex 'handle 11 stop' -ex 'cont' -ex 'bt full' -ex 'cont'
In any case, either your suggestion or mine have to be run as root.
