Bug 483247

SUMMARY
It adds about 30 seconds extra to login (via SDDM).


STEPS TO REPRODUCE
1.  Enable splash screen (either in the systemsettings or with "systemctl --user unmask plasma-ksplash.service")
2.  Logout from plasma and the log back in while taking the time
3. Disable splash screen (either in the systemsettings or with "systemctl --user mask plasma-ksplash.service")
4.  Logout from plasma and the log back in while taking the time

OBSERVED RESULT
When enabled, the splash screen adds about 30 seconds to login, while it takes a few seconds without.

EXPECTED RESULT
Negligible differences between the two cases.
