Crashing in KConfig:

> #4  0x00007f006dab3ae6 in KConfigBase::group(char const*) () at /usr/lib64/libKF5ConfigCore.so.5
> #5  0x00007f006f205f8a in SessionBackend::confirmLogout() const () at /usr/lib64/libkworkspace5.so.5
> #6  0x00007f006f202f05 in SessionManagement::requestLogout(SessionManagement::ConfirmationMode) () at /usr/lib64/libkworkspace5.so.5

I seem to recall some changes here regarding group property access; moving to KConfig.

Would be interesting to know if it still happens in Frameworks 5.94 as I see at least one related commit. Can you try that?
