Application that crashed: umbrello Version of the application: 2.3.0 KDE Version: 4.3.00 (KDE 4.3.0) "release 152" Qt Version: 4.5.2 Operating System: Linux 2.6.27.25-0.1-default x86_64 Distribution: "openSUSE 11.1 (x86_64)" What I was doing when the application crashed: Clicked the "100% zoom button" on the toolbar with no document open. Repro steps: -create/open a document, and click on it so that is considered modified -click file->open, and discard/delete the document when prompted. This closes the previous document. -cancel the file-open dialog. At the point, the previous empty document has been closed. -click "zoom to 100%" on the toolbar to crash. -- Backtrace: Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault [KCrash Handler] #5 0x00007faebf4b2de9 in Q3CanvasView::setWorldMatrix(QMatrix const&) () from /usr/lib64/libQt3Support.so.4 #6 0x0000000000c4d746 in ??
