Review request for K3b.


Bugs: 323117
    http://bugs.kde.org/show_bug.cgi?id=323117


Repository: k3b


Description
-------

It happens that the first remove of song deletes the parent model so the rest of subsequent removes go back to the parent model, try to delete themselves from it and they are already gone.


Diffs
-----

  src/k3bmetaitemmodel.cpp 8101596 

Diff: https://git.reviewboard.kde.org/r/120607/diff/


Testing
-------

Create a mixed mode CD.

Add three songs to the audio section
Select two songs
Remove them

Without the patch it crashes, with it works fine


Thanks,

Albert Astals Cid
