--- Comment #16 from caulier.gil...@gmail.com --- Qt said that QVector are used out on index. This is an internal use, not from digiKam. The Digikam::AbstractAlbumModel::slotAlbumAboutToBeAdded is called with these arguments (this=0x1390690, album=0x21f7de0, parent=0x21f6410, prev=0x0) prev = 0 wnat mean that a parent album must be registered in model. Code relevant from digiKam is here : https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/libs/models/abstractalbummodel.cpp#L422 This call Qt like this QAbstractItemModel::beginInsertRows (this=0x1390690, parent=..., first=0, last=0) ...and it crash. Note that first and last are null, which is fine with Qt API : http://doc.qt.io/qt-5/qabstractitemmodel.html#beginInsertRows Gilles Caulier -- You are receiving this mail because: You are watching all bug changes.
