Just a stab in the dark, but... what's the value of
'CSResourcesFileMapped' in your Info.plist?  If it's "true" or not
there, maybe some code is assuming it can modify the contents of a
resource?  On PPC, such resources are mapped into memory that's read-
only, and you'd get a access violation, but on Intel, you don't.  But
your changes aren't saved to disk (but you probably wouldn't want
them to be, so that's why this is such a SWAG).

Post a stack crawl or two from the crashes, that would help...
