The import creates many undo entries and I jumped to the first entry of the undo list. The crash can be reproduced every time. -- Backtrace: Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Further digging into this problem shows, that at least in CmdSetStereotype and CmdSetVisible the stored uml object pointer isn't valid, which results into the crash.

Disable undo while code importing to not pollute the undo stack. The drawback is, that not all widgets could be undo'ed and may confuse users. May be better to merge one import into one undo entry.
