Same problem here with dvb-daemon 0.1.23 after upgrade to glib 2.28 under gentoo:

debug-epg_disabled.txt Edit (1.7 KiB, text/plain)

The error occurs right after program start. It must have something to do with epg, because there is no error if I start with --disable-epg-scanner (see attachment).

version 0.1.90 (I have not tried other versions)

steps to reproduce: start gnome-dvb-daemon
how often it happens: always or almost always
notes: there might be bugs in the ttusb_dec driver as well (i've never managed to watch tv on linux using that device, it works fine on windows)

and least but not last: it also happens when EPG scan is disabled.

Could please create a core dump with gdb by running "generate-core-file" inside of gdb when the program crashes and upload it here.

Could you please provide a patch against 0.1.23. The git version does not compile on my system due to pygobject < 2.28.
