Compilation went fine, all the features worked and stuff. I listened
for maybe an hour and then I got the attached crash.
The issue, I think, is that the station I was listening to became "out
of tracks." This happens some times when you listen long enough that
you exhaust all songs you can listen to on that particular station for
some unknown time. Since the backtrace below indicates it died when
parsing some XML, perhaps liblastfm is trying to fetchMoreTracks and
it fails? Dunno, that's just me speculating. I attached Max to this
message.
