I would say that's not a valid stack trace.  There hasn't been a
change made to that file since October of last year, and the crash is
apparently recent; also, line 1250 in that file doesn't look like
something that can crash.  I would guess that you're using an
executable which doesn't match the core dump, or perhaps that you
don't have complete debug symbols.  Building with -O0 might help.
