Tvheadend

TVH aborts if I try to delete a 'Series Link' autorec (with no pending timers) using the HTTP API eg:
curl http://user:[email protected]:9981/api/dvr/entry/cancel?uuid=3c2cad4db51c1c6c5a368cfb877af538

The core dump backtrace is:
Core was generated by `./tvheadend -d --http_root /vdradmin'.
Program terminated with signal SIGABRT, Aborted.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

It seems that the code is not written to handle deletion of autorec timers, but perhaps aborting is not the best solution
