[mythtv] mythfrontend crashes when watching recording from "Das Erste HD" / Germany

[cptspock at gmx.de]

Hello!

Since my latest update today I have the following problem. I'm using latest 
trunk version from git and compile the sources myself. Before todays update I 
used this trunk version: [v0.25pre-943-ged49c2b]. With the old version 
everything was all right.

When I want to watch a recording from channel "Das Erste HD" (Germany) 
mythfrontend craches immediately. I can't find a clue in the logs. Here is what 
I have. This only happens with recordings from this channel. I can watch all 
other recordings, including HD, from other channels.

my system
---------
OpenSuSE 11.3 with all updates
Kernel 2.6.34.7-0.7-default
GPU NVidia Quadro FX380, PCI-E with proprietary nvidia driver
I am using vdpau for all videoplayback.

Here are the log from the mythfrontend-session before it segfaults and the 
backtrace output from gdb. I hope these are the necessary information.
