Unfortunately it looks like SUSE's emacs is compiled without debugging
symbols. Here's a stack trace of the crash...

Program received signal SIGSEGV, Segmentation fault.

Previous frame identical to this frame (corrupt stack?)

I imagine this isn't very helpful.  I'll grab the sources, build my
own Emacs, and see if the problem remains.
