I think I found the source of the error:<br>
<br>
TrackRole is defined as Qt::UserRole which was 32 in qt4 and which
now is 0x100 = 246 = Playlist::GroupRole<br>
<br>
So we have this strange loop... <br>
<br>
I tried with Playlist::GroupRole = 0x1000 and it works (for this
part). Is it ok if I leave it like this?<br>
<br>
Cheers<br>

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