I've heard a rumor that it's really a bink video bug, and your report helps confirm this. It's not surprising for an app bug to be nondeterministic...
Tempting to mark this bug NOT A WINE BUG, but I can't quite be sure.
Actually, it first happened for me when switching from the 2.6.31-11 rt kernel in ubuntu, to one of the newer generic ones. Works fine in the older kernel, just quite a bit slower.
