I tried 0.1.15 and the same crash did not happen. However, gnome-dvb-daemon crashed so gnome-dvb-setup could not exit and I got this error every time I tried to close the window or click the "Close" button, "org.freedesktop.DBus.Error.ServiceUnknown: The name :1.142 was not provided by any .service files". Had to kill gnome-dvb-setup and restart gnome-dvb-daemon but this time it looked like it had channels.

For some reason apport did not fire. The totem plugin does not seem to work when manually installed, I think that this is because it does to /usr/local, maybe. Any ideas?

The error you described is expected when the daemon crashes. It would be great if you could provide a stacktrace of the daemon's crash.

Regarding the Totem plugin, looks like you have to use --prefix=/usr when running configure

Sorry, but I failed to reproduce the crash with neither 0.1.15 from the tarball nor the bzr version.
