            Bug ID: 350986
           Summary: Umbrello crashed when moving a 'frozen' label
           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: aureate.tongues at gmail.com

Application: umbrello (2.14.3)
KDE Platform Version: 4.14.3 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Linux 4.0.5-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
The document was acting strangely up until this point: dragging about 5 class
boxes around at once didn't maintain relative distances between some of them,
and dragging class relationship labels either occasionally didn't work at all
or they appeared to 'jump' to some x or y off the visible section of the map. 

Umbrello then crashed upon clicking and attempting to drag the 'frozen' label
of one of these relationships.

The crash can be reproduced every time.

-- Backtrace:
Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
