            Bug ID: 443580
           Summary: Crashes on cancelling the creation of a new class with
                    the "Creation" tool in sequence diagram
           Product: umbrello
           Version: 2.32.0 (KDE releases 20.08.0)
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: umbrello-devel at kde.org
          Reporter: bingtimren at gmail.com
  Target Milestone: ---

SUMMARY


STEPS TO REPRODUCE
1. Create a sequence diagram 
2. Create a new class "new_class" in the sequence diagram
3. Select "Creation" (the dashed arrow line) from toolbar
4. Click on the lifeline of the "new_class" and extend the line to the right,
click again, the "New class" dialog pops up, asking the name of the new class
5. Press "ESC", or click "Cancel" or the "close" button to cancel the operation


OBSERVED RESULT

Crashes


EXPECTED RESULT


SOFTWARE/OS VERSIONS
Windows: X11
macOS: 
Linux/KDE Plasma: Ubuntu 20.04.3 LTS
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION

I don't know how to find the KDE & QT version information of my system. Ubuntu
seems to use Gnome not KDE. Checking the installed packages it seems that KDE
Framework 5 & QT 5 are installed but I'm not sure. Also I cannot find the core
dump file. Hope you can duplicate the crash on your end. 

console output is as follows:
