I think the problem was a memory-management issue in the JPEG binding, since the crash I provoked was in libjpeg.
After fixing that problem (pushed to the git repo), I'm no longer able to provoke a crash. I'd appreciate further checking with the latest sources or the next nightly build by anyone who was able to provoke the crash before.
