Hi,
the error I was tracking occures in
src/playlist/proxymodels/GroupingProxy.cpp
Meta::TrackPtr prevTrack = prevIndex.data( TrackRole
).value<Meta::TrackPtr>(); // Invalid index is OK:
Meta::TrackPtr thisTrack = thisIndex.data( TrackRole
).value<Meta::TrackPtr>(); // will just give an
Meta::TrackPtr nextTrack = nextIndex.data( TrackRole
).value<Meta::TrackPtr>(); // invalid TrackPtr.
Here is the begining of my backtrace.... Any help is welcomed...
