Frameworks Version: 5.54.0
Operating System: Linux 4.9.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:
After login, when KDE desktop builds desktop
- Unusual behavior I noticed:
1) long (more than 60 seconds) time between entering login data and ready to go
2) logoff/crash of session when loggin in from lock-screen (Sperrbildschirm, ger)
- Custom settings of the application:
since upgrade from debian 9 to debian 10

The crash can be reproduced sometimes.
