darktable crashed with SIGSEGV in _lib_backgroundjobs_destroy()

[Jason Gerard DeRose]

With darktable 1.2.2-2ubuntu1 in Saucy, I get a segfault whenever I try to export Canon RAW files. This might effect other RAW formats as well, but I don't have any handy to test with.

Can you attach an example file that causes the crash? I tried opening a random DNG of mine and it was fine.

More information was requested (should've been marked incomplete) and not provided. This is an ancient version of Darktable, and Ubuntu 13.10 is long since EOL. Closing.
