"$ systemsettings5 --version" OBSERVED RESULT What seems like a crash on step #2 System settings does not launch on step #3 On step #4: > Please instantiate the QApplication object first On step #5: > Please instantiate the QApplication object first and no output about the version EXPECTED RESULT "System settings" application does not crash after step #1 "System settings" application launches on steps #3 and #4.
