Version: (using KDE Devel) Installed from: Compiled sources OS: MS Windows When KIconLoader tries to load an icon which is not available (however this can be), it tries to insert a null pixmap into K/QPixmapcache. This fails in QDetachedPixmap ctor on windows (qpixmapcache.cpp:94). It's more a qt bug but I wonder if it's correct trying to insert a null pixmap into the cache. I'll report this to qt-bugs too
Fixed in Qt.
