-- Information about the crash:
- Custom settings of the application:
The issue started after manually upgraded fedora 33 to 34. On first deleting the konsolerc file in .config folder, the app started but  after i created a custom profile in the konsole app and activating the profile, the app crashed immediately. 
Any more deleting of the konsole configs file doesn't solve the crash.
Even after installing Fedora 34 afresh the issue persists after creating a new profile.

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
