Assuming you have core dumps enabled, start it from the command line so 
you can run
"gdb -c core.nnnn" and then issue the command "backtrace".  To get nicer 
diagnostics you need the symbol tables etc., I'm not sure if Debian 
produces the equivalent of the "debug" rpms I get.  Further reading of 
the gdb man page will show you how you can get the source lines relevant 
to the trace as well.  So long since I used that I have forgotten it all.
Beyond seeing the called parameters of the seg-faulting routine you 
would need to put breakpoints on the elisp interpreter, and I not going 
there.
