Application: umbrello (2.18.3) KDE Platform Version: 4.14.33 Qt Version: 4.8.7 Operating System: Linux 4.4.159-73-default x86_64 Distribution: "openSUSE Leap 42.3" -- Information about the crash: - What I was doing when the application crashed: Rearranging a class diagram containing 7 classes. Nothing unusual about the diagram, still in the early stages of designing that application. Cannot set up a reliable test case as the fault seems intermittent. Changing the layout works most of the time. May be it is due to me changing the layout when a timed Save Changes operation starts - not sure. There was some disk activity at the time of the fault. Might be worth trying an interlock causing the layout functions to wait for the save to complete and to make the timed save wait until user interaction has stopped albeit briefly. -- Just a thought, no evidence that this might work. The crash can be reproduced sometimes. -- Backtrace: Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
