Cannot change channels after some time

[Jens Georg <mail jensge org>]

I'm using gnome-dvb-daemon together with Rygel to distribute live DVB-T
through my home network, this works quite well, but after changing the
channel several times, I run into this:

default      DEBUG      ChannelFactory.vala:568: Watching channel ProSieben (16403)

(gnome-dvb-daemon:29251): GLib-GObject-CRITICAL **: g_object_set_qdata: assertion `G_IS_OBJECT (object)' failed

The error message differs, sometimes it's something with "cannot open device".

This is on Debian unstable. I'll try to get a backtrace at the first critical.
