-- Information about the crash:
SUMMARY

Sometimes, when trying to close an application via the task manager context menu, the plasma shell freezes and crashes. with the cursor turning into an "X" and then it crashes. The shell restarts afterwards.

STEPS TO REPRODUCE

1. Open an application
2. Right click the icon of the program
3. Click "Close"

OBSERVED RESULT

The plasma shell freezes with the cursor turning into an "X" on the panel. After a few seconds, it crashes. The shell restarts afterwards. The application that I tried to close didn't and remains open after the restart.

EXPECTED RESULT

The application closes.

The crash can be reproduced sometimes.
