Now and then when I open a video in VLC or try to record something in Cheese, Compiz crashes, which therefore causes Emerald to crash, etc. I have to restart my computer to get things looking right again. This is the error I get in syslog:

Code:
brian-desktop kernel: [14248.020737] compiz.real[1763]: segfault at 8 ip 01a3b2c5 sp bfb6d604 error 4 in libGLcore.so.185.18.36[ff0000+d6f000]
Any idea why this is happening or how I can fix it?
