           Summary: Plasma crashes when trying to configure desktop
                    settings
           Product: kde
           Version: unspecified
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR

  Target Milestone: ---

I've installed a minimal Plasma 5 on my Archlinux system. Everything works
fine, but when I try to change a wallpaper by clicking on corresponding menu
item, Plasma crashes and then restarts. So, I'm unable to change my desktop
settings.

When I start plasmashell with gdb and try to get desktop settings again, it
fails with such output:
