Perhaps unrelated, but if one has tried to do something else before quitting,
like opening/closing composer, the crash seems to be: 
Program received signal SIGSEGV, Segmentation fault.
0x40d3058a in NSGetModule () from /tmp/package/components/libgklayout.so

I've had around 30-40 crashes, seemingly unrelated, but all in libgklayout.so
the past 24 hours (last two builds)

i see a checkin (-out, rather) of nsDnsService.cpp by mscott at 01:29 with
comment: "Backing out gagan's check in as this causes linux to crash on exit"

This bug may be fixed already..
