I have my window-manager, fvwm, configured to play a sound with aplay
when a new window is opened. The crash don't occur if I turn off the
sound-playing at window-open.

The problem might be in xine, but as the crash is in libasound2 and
only occur when playing another sound at the same time...

I'm using the via82xx-driver compiled into 2.6.5.

I seems to be fixed! I can't repeate it any more with 1.0.6,
=> closing this report!

Tanks!
