Yes, otherwise valgrind wouldn't complain. Anyway, I don't think valgrind could
help finding this...
I now recompiled Qt with CXXFLAGS="-O0 -g -DQT_DEBUG" and got some better
backtrace:
ASSERT failure in QVector<T>::at: "index out of range", file
../../include/QtCore/../../src/corelib/tools/qvector.h, line 393
