I would suggest (but without detailed knowledge of current emacs practice):

1. Report your exact emacs version.

2. Install a corresponding debug symbols package, if your distro 
provides that.  That should add a lot more interesting detail to the 
backtrace.

3. To go further, repro under GDB, ideally with corresponding source 
code.  Then you could explore the immediate cause of the segfault.
