           Summary: Undoing synchronous messages in sequence diagram
           Product: umbrello
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel at kde.org
        ReportedBy: olli.myohanen at welho.com


Application: umbrello (2.4.5)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-30-generic x86_64
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
I tried to create a sequence diagram with several "overlapping" synchronous
messages. Umbrello was not exactly doing what I was hoping for and it ended up
in bit of a mess. I tried to press Undo several times to get rid of the changes
and that's when the program crashed. 

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