Tvheadend

I deleted channels over that Configuration -> Channels menu. After some time I get the message "There seems to be a problem with the live update feed from Tvheadend. Trying to reconnect..." in the system log of Tvheadend and the program crashed:

When I restart Tvheadend with '/etc/init.d/tvheadend restart' everything works fine until I do some more delete tasks.

I'm using Debian 7 'Wheezy' on Linux vdr 3.2.0-3-686-pae #1 SMP Thu Jun 28 08:56:46 UTC 2012 i686 GNU/Linux. I installed tvheadend over http://www.lonelycoder.com/debian/ repository.
