Tvheadend

One of the TVHeadend instances I operate aborted with the following in the logs earlier today:

I had just upgraded it from a version about a week old, so I suspect one of the recent changes to "tsfix" may be at fault since I had never seen such a crash before. I attempted to reproduce the crash for quite some time with a debugger attached, but I have so far been unable to. If I am, I will update the bug report with a stacktrace.
