Version: 2.0 beta-5 (using 4.1.2 (KDE 4.1.2), Kubuntu packages) Compiler: gcc OS: Linux (i686) release 2.6.24-23-generic to reproduce: 1. start a new document 2. lock the layer with the tablet stylus 3. move to stylus to the canvas 4. crash the crash happens immediately after the stylus enters the canvas while the layer is locked, if you just lock and unlock without the stylus reaching the canvas there's no crash, if you lock with the stylus and switch to mouse there's no crash either. backtrace: Application: Krita (krita), signal SIGSEGV [Thread debugging using libthread_db enabled] [New Thread 0xb3f35900 (LWP 14363)] [KCrash handler] #6 0xb68f1a71 in KoToolProxy::Private::checkAutoScroll (this=0x8b76c00, event=@0xbfe4c6f0) at /home/m4v-kde3/dev/kde/src/koffice/trunk/libs/flake/KoToolProxy.cpp:116 #7 0xb68f1252 in KoToolProxy::tabletEvent (this=0x8b76b98, event=0xbfe4ccb0, point=@0xbfe4c760) at /home/m4v-kde3/dev/kde/src/koffice/trunk/libs/flake/KoToolProxy.cpp:203 #8 0xb7ac738d in KisQPainterCanvas::tabletEvent (this=0x8b76e08, e=0xbfe4ccb0) at /home/m4v-kde3/dev/kde/src/koffice/trunk/krita/ui/canvas/kis_qpainter_canvas.cpp:281 #9 0xb5f5fbd9 in QWidget::event () from /usr/lib/libQtGui.so.4 #10 0xb5f07f9c in QApplicationPrivate::notify_helper () from /usr/lib/libQtGui.so.4 #11 0xb5f0d676 in QApplication::notify () from /usr/lib/libQtGui.so.4 #12 0xb750d483 in KApplication::notify () from /usr/lib/kde4/lib/libkdeui.so.5 #13 0xb7dea0b9 in QCoreApplication::notifyInternal () from /usr/lib/libQtCore.so.4 #14 0xb5f661ec in ??
