-- Information about the crash:
- What I was doing when the application crashed:
I does changes in System Setting aplication in part for default aplications after Account details.
I clicked one tab by one. After this I close Default Aplications by Back button in header and aplication crush.

- Unusual behavior I noticed:
There is written in Account Settings to login user during start, but firs I everytime have to do after upgrade is to login.

-- Backtrace:
Application: Nastavení systému (systemsettings5), signal: Segmentation fault
