Hmmm, the backtrace here is interesting. This may be related to Qt 4.4's alien widgets. What apparently happens is that Kompare calls KIO::NetAccess::upload, which is expected to handle all the uploading and return only when done. However, KIO::SchedulerPrivate::registerWindow requests a winId for a widget, which in turn causes the widget to be instantiated (by QWidget::create), and there we hit a segfault in X11-specific code. Unfortunately, the backtrace doesn't tell me more, so I'm not sure what exactly causes this.
