Main Cue point not stored

[ronso0]

Just started over with a blank profile & database to reproduce this:
* load a new track (never played, not analyzed yet) to a deck
* set HotCues, set main Cue point
* unload track, load again
> Cue point still present

* close & re-launch Mixxx
* load that track
* main Cue point gone/reset to first frame of track
All HotCues are stored correctly.

See attached log.
In only 1 out of 5 attempts this showed up when shutting down:
Debug [Main]: TrackDAO: Updating track in database "/mnt/M_OOLI/audio/00__mu__iN/00__neo/ Sigaah - Chinese Food xXx.mp3"
Debug [Main]: "INSERT INTO cues (track_id, type, position, length, hotcue, label, color) VALUES (?, ?, ?, ?, ?, ?, ?)" QSqlError(19, "Unable to fetch row", "NOT NULL constraint failed: cues.label")
Debug [Main]: Committing transaction on "qt_sql_default_connection" result: true

EDIT
I can't recall with which version this behaviour started.
I just restored my working profile and notice that (on 'old' tracks) the respective main Cue points are restored correctly as I previously set them (looong ago). But changing their position doesn't work, as described above.

Fixes only the NOT NULL issue, cue point handling is still buggy:
