As 2 different users tested and got a crash (original reporter and
another one), I assumed that was not specific to a particular disk.
It seemed not specific to graphic card either, as one had an NVidia with
the proprietary driver using X11 and another with an AMD with the radeon
driver using Wayland.
I am myself using another AMD card with the radeon driver and X11.
However, vdpau was involved and xshm was not crashing.

Actually, this was already fixed with 14200. So something between 1.2.9
release and revision 14200 fixed the crash already. Sorry for failing to
mention the revision of the snapshot I provided the user with.

No DVB available either, but I'll provide an updated build to the user
to test (building 14229 right now).
