           Summary: crash when moving all elements in a sequence diagram
           Product: umbrello
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: umbrello-devel.kde.org
        ReportedBy: tonton-lists team1664 org


Version:           1.5.6 (using KDE KDE 3.5.6)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc 4.1.2 debian unstable
OS:                Linux

When moving all the elements in a sequence diagram, umbrello eats all available memory and crash with a bad_alloc exception. I'm unable to reproduce this bug on a 32 bits system, but it crashes all the time on my 64 bits core 2 duo, even with a svn snapshot.

How to reproduce :
- limit the memory available for the program to not freeze your system (ulimit -v 500000)
- launch umbrello --nocrashhandler
- create a sequence diagram
- create three objects
- connect the 1st object to the 2nd, and the 2nd to the 3rd (the type of message is not important)
- select everything on the sheet
- try to move all the objects
- crash

Backtrace is attached.
