During generation of mood files some mood file was not generated properly for some reason and it had 0 size. When I enabled moodbar in clementine 1.1.1 from testing and song with that file was displayed in the playlist, clementine crashed with: 14:37:50.282 ERROR unknown ASSERT failure in QVector<T>::operator[]: "index out of range", file /usr/include/qt4/QtCore/qvector.h, line 355 Neúspěšně ukončen (SIGABRT) Steps to reproduce. 1) Enable moodbar in Clementine 2) Enable display if moodbar in playlist 3) Create empty .mood file for some song (simple "touch .song.mood" should be enough) 4) Add that song to the playlist Clementine would crash right away.
Does it still happen with version 1.2.1? If yes, please report upstream.
