Comment 1 Daniel Faust 2010-09-26 18:52:58 UTC

As far as I can see, this crash happened before markey re-added his fix for applets being loaded twice.
Anyway, I just committed a new version of the labels applet that doesn't even contain the LabelsApplet::engineNewTrackPlaying function anymore.
So this bug should be fixed.
