Panel crashes after exiting mplayer.

[Marc Hildebrand]

Hi!

I'm using xfce4 from cvs (co Sunday).
When I start mplayer from a launcher or an xterm, the panel crashes after
exiting from mplayer.
The mplayer is: "MPlayer 0.90-3.2.3".
I'd like to trace the crash back but don't know how. (I'm not a coder)
Any hint would be welcome!

A sidenote: after the crash there's no "Desktop left- or right-click 
menu" anymore.

I'll check a few other apps to repoduce this behavior, till now it only
occurs with mplayer.
Greets,
Marc.
