Crash on slower system in replace-and-play mode

[GoogleCodeExporter]

What steps will reproduce the problem?
Only happens on my slower system (via c3 1Ghz)
1. Play a file in gnome-mplayer 
2. Start another 'gnome-mplayer media2.mp3' this will contact the running
instance of gnome-mplayer and replace the file playing with media2.mp3
3. Crash (segfault) of first instance of gnome-mplayer

What version of the product are you using? On what operating system?
0.9.6

Please provide any additional information below.

I suspect this is caused by some race condition and hence only showing on
slower systems. From the coredump I obtained the following trace:

Core was generated by `gnome-mplayer'.
Program terminated with signal 11, Segmentation fault.

Attached also the command line output of the first instance of gnome-mplayer.

The same crash also happens in combination with gecko-mediaplayer using the
javascript function Open() while the player is currently playing another file.

I downclocked my machine to 1.6Ghz and can't duplicate the issue. But I did add 
a
validation check to the code at gui.c line 345 to help prevent this issue.

• Changed state: Fixed

1.6 GHz is probably still to fast to let this occur. On a laptop with a 1.6Ghz
celeron this problem does not occur either.

But I'm happy to report the check prevents the crash on the 1GHz c3 via system. 
Thanks!
