It looks like it is blowing the stack.
Ideas?

Let me guess: this is on FC2?

No, as mentioned it's SuSE 9.0.

One more thing: about 1 in 5 runs it turns out that wine does start.
Never under strace, though.

/me smells a race condition.

I'll just add a "me too" to that one. I have not tried putting numbers 
to it, so I don't know whether it is 1 in 5. But I have already gotten 
accustomed to just rerunning a program that doesn't start up. This on RH9.
