    Description

      When using QT5 5.12.3 or newer The breeze theme for SDDM will cause problems.
      It will cause SDDM to crash whenever the user clicks on the "different user" button at the login screen. This bug does not happen with QT5 5.12.2 or lower or any other SDDM theme such as elarun, pretty sure its a compatibility issue of
      sddm-theme-breeze and QT5 >= 5.12.3. The current QT 5.13 beta builds do not work, either.

      Both KDE and SDDM developers believe that the problem is not being caused by them, but by QT:

      The First bug report contains a detailed crash report of QT/QML.

      Thanks for your efforts in advance
