Bug#376188: xserver aborts with sigsegv when xawtv starts

[Matthieu Lochegnies <prof@dictature.org>]

Hi,

I've just reproduced the bug, with 1.3.0.0.dfsg-12.

After gdb showed me where the segfault occurs, I wrote a very quick
patch that seems to fix the problem, but dont ask what causes it.

Cheers,
