I've filed a bug here listing problems when some part of the KDE/Qt system appears to be replacing QFileDialog (the Qt file dialog) with KFileDialog (the KDE file dialog) in my Qt/PyQt application: https://bugzilla.redhat.com/show_bug.cgi?id=570090 I've filed this under Qt, but maybe someone knows whether it is KDE doing this, and whether it is possible to turn off this (currently) buggy behaviour, at least for my application. Thanks Jeremy
