Tvheadend

I've been experiencing queue related crashes since commit 2dfc27 up until master but at different locations. I'm running Debian "testing" but there haven't been any changes to sys/queue.h as far as I could see. I've tried hunting the bug down but no luck. Here's the backtrace from master:
