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:

Git commit f2c182d21684c0be6241916155f48bcbc64f2d8a by Oliver Kellogg.
Committed on 11/02/2022 at 20:48.
Pushed by okellogg into branch 'master'.

Fix 'Crashes on cancelling the creation of a new class with the "Creation" tool in sequence diagram'

umbrello/toolbarstatemessages.cpp
- In function mouseReleaseEmpty test return value from
  Object_Factory::createUMLObject() to be non null.
  If null then do not call Widget_Factory::createWidget and its follow-
  on operations.

umbrello/object_factory.cpp
- At function createUMLObject document the fact that the function may
  return nullptr.
FIXED-IN:2.33.80 (KDE releases 22.03.80)
