Uff, can confirm. Handling the result of QHash::find in #11764 is wrong, it'll crash with nonexistant property string.
I'm about to fix it.
This reveals another issue: at least LateNight uses titleInfo instead of title for track labels. Not sure if it was always like that, or if I changed that in the LateNight redesign, and if so why.

@stefan-franz Unfortunately there's no consecutive list of builds in http://ppa.launchpad.net/mixxx/mixxxbetas/ubuntu/pool/main/m/mixxx/, so the last version without this PR is mixxx_2.4~beta~60

okay, all skins use this in decks and samplers, so I'll simply forward titleInfo to the track title field.

fixed by #11804

Linux Mint doesn't find an update to download. Not fixed at the moment.
