[MPlayer-advusers] gmplayer crashes on startup

[f.seydel at crushed-eyes.com]

Hi folks.

I'm using gmplayer as a viewer for an encoding pipeline faciliating mencoder.
As I'm always adding new features to the pipeline, I have to recompile  
mplayer once in a while.
Everything has been running plain smooth for the last two years and I  
had been able to solve all problems myself until now.

But now I'm stuck, I can't get gmplayer to run anymore!
mplayer works fine.

Problems started two weeks ago, after recompiling mplayer with latest  
svn version the skin file wouldn't load due to some PNG format error  
(alpha channels, seemed to be an well-known older problem).
Now this bug seems to be fixed but gmplayer just crashes on startup.
I already tried to to compile and run on different machines - same crash.
I also tried different skins ("Blue", "Blue small", "Canary") - same crash.
I have changed the video mode by editing ~/.mplayer/gui.conf, from x11  
to xv - same crash.

I'm at a loss, can you help out?

Can you reproduce the bug or am I doing something terribly wrong???

Thanks in advance!
