Comment # 2 on bug 1000917 from Larry Finger

Changing the theme did not help.  The output of 'gdb sddm' follows:

Reading symbols from sddm...(no debugging symbols found)...done.
Missing separate debuginfos, use: zypper install

Do you need me to install a debugging package for sddm? If so, which one?
