#25 Crash on quickly clicking next through gallery

[Declan McGrath]

Not sure why this happens but I tried to put in code to guard against the index going over the length of the imagelist and that didn't help. I think we may just have to put a pause in the user interface to slow down moving through images (or else change preload images and totally change the architecture - I don't like this option!).

The error message issued is

ASSERT failure in QList<T>::operator[]: "index out of range", file /mnt/extra/NotBackedUp/qt4-built/Trolltech/Qt-4.3.0/include/QtCore/../../src/corelib/tools/qlist.h, line 379
