            Bug ID: 347356
           Summary: Umbrello crashes when closing the application
           Product: umbrello
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: umbrello-devel at kde.org
          Reporter: gbonnema at xs4all.nl

Application: umbrello (2.16.99-1088e8b)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.5-200.fc21.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Steps to create the abort:

1. Start Umbrello
2. Create a Test Class
3. Add one attribute (public)
4. Close application
5. Chose to discard changes.

This is when the abort took place. I did it twice in succession. I did not test
any other combination of actions.

- Custom settings of the application:
I use the Umbrello (updated version) from a git repo of Umbrello in stead of
the Fedora standard version.

The crash can be reproduced every time.

-- Backtrace:
Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault
