Drawing crash - not near my code!

Does anybody have any idea why this crash is happening? It's
happening to one of my users somewhat randomly, and the crash report
isn't touching any of my code-- all the other threads in the app are
fine, waiting at message traps.
The reason why I ask here is that it's coming from objects
(NSFocusState, NSFrameView) which have no documentation *at all*, and
even weirder, it's crashing at a *math statement* in libmath!.
My app is compiled for PPC and i386, and I recognize the math stuff
as being a "warning sign" for running on i386 (divide by zero, etc) -
but it's running on a PPC, so the i386 code isn't being touched.
Anybody recognize what's going on here?
