It would be nice to get a stack trace to be able to get an idea where the crash happens for example by running umbrello with gdb. Created attachment 102852 [details]
Crash backtrace
Comment on attachment 102852 [details] Crash backtrace >/usr/lib/libQtGui.so.4 This is a Qt4 build which differs from the initial description #0 .. __cxxabiv1::__dynamic_cast(void const*,...) (src_ptr=0x0,...) #1 .. in UMLObject::asUMLClassifier() (this=<optimized out>) at /home/daniel/builds/CUSTOM/umbrello/umbrello/umlmodel/umlobject.cpp:1236 #2 .. in UMLClassifierListItem::getType() const (this=this@entry=0x15baab0) at /home/daniel/builds/CUSTOM/umbrello/umbrello/umlmodel/classifierlistitem.cpp:103 This indicates that UMLObject::asUMLClassifier() got a zero pointer at UMLClassifier * UMLClassifierListItem::getType() const { return m_pSecondary->asUMLClassifier(); } Git commit ee3d370f5818c70a69525bb1232ae71b0921a75a by Ralf Habacker. Committed on 19/12/2016 at 07:55. Pushed by habacker into branch 'Applications/16.12'. Fix 'Application crashes when opening an UML/XMI class diagram'. Add check to avoid accessing zero m_pSecondary.
