Yeah, that would certainly be the first thing to try.  If the problem is
still there, we'd really need quite a bit more information to diagnose
it.  A stack trace from the point of the crash would be quite helpful:

Even better would be if you can reduce the problem to a self-contained
test case, though I realize that might be hard.
