            Bug ID: 329648
           Summary: Crash on undo after source code import
    Classification: Unclassified
           Product: umbrello
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: umbrello-devel at kde.org
          Reporter: ralf.habacker at freenet.de

Application: umbrello (2.12.99-e34eb23)
KDE Platform Version: 4.11.3 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.4.47-2.38-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I imported umbrello/widgets/artifactwidget.h and umbrello/widgets/actorwidget.h
from the umbrello source code. 
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
