Comment (by danielk):

 There are no invalid writes in that valgrind log, which is what I was
 hoping for.

 There are plenty of double frees, mostly due to using QString's accross
 threads without making a deep copy. But these usually don't cause a
 SEGFAULT.

 Can you set the environment variable MALLOC_CHECK_ to '1' and see if you
 can reproduce the crash? If no, please send me the backend's "-v record"
 log with the malloc messages embedded (which may be redirected to stderr
 rather than stdout.) If you can still cause the crash, can you try setting
 MALLOC_CHECK_ to '2' and get a backtrace from that.
