Comment(by Derek Atkins <warlord at mit.edu>):
Okay, upgrading to r13782 didn't solve the problem, and indeed introduced
many more problems. For one thing, the audio has many more noises
('pops') than it did before, and the system STILL crashed with a SEGV in
approximately the same place. The frontend log also has this (it had this
last time, too):
2007-06-29 14:16:19.025 VideoOutputXv Error: CreateXvShmImages():
XvShmCreateImage() failed to create image of the requested size.
2007-06-29 14:16:19.025 VideoOutputXv Error: CreateXvShmImages():
XvShmCreateImage() failed to create image.
Stack trace:
Program received signal SIGSEGV, Segmentation fault.
