OK, traced this down to some 0 byte recording files in the record directory.
Pressing "recorded programs" tried to generate previews for these and the
backend crashed. Couldn't get it to crash under gdb though, so I have no
indication of clue to where the crash was, sorry.

I am quite worried about my stack trace not having symbols though.
Doublechecked and the backend is not stripped and configured with
--compile-type=debug. Any clues for the future?
