Sounds good to me, yet (while you're at it) it would probably be the
exact same issue for trying to add entries to shedule recordings of
live TV, where I first noticed the issue, i.e. a single entry for a
single recording can be added (as is the case for channels), but trying
to shedule yet another recording crashes kaffeine.

The program is next to unusable under Wayland anyway, because besides
a video window showing up separately, even scrolling channel lists or
merely showing them is a bit like a fight, requiring mouse klicks
into the list to make it update the entry you just clicked, changing
the text to what it actually should be, but there simply is no
replacement for live TV on the desktop I'm aware of, unfortunately,
so no matter how unusable it is, it would still be really nice if that
could at least be made to work again somehow without crashing - no
matter how broken that ancient, seemingly abandoned code base is.

It's a glaring hole in Gnome, though and projects trying to tackle
it never really got to the point of delivering what kaffeine did and
died. Most notably was MeTV, IMHO, but that's also ancient history
by now.

Anyway - any efforts to at least make it „work“ again will be much
appreciated. <3

Kind Regards,
