Comment # 8 on bug 932630 from Josef Reidinger

OK, so if you can provide output of 

ls -l /usr/share/YaST2/clients

and

ls -l /usr/local/share/YaST2/clients


you can also try who own you bootloader component like this

rpm -qf /usr/share/YaST2/clients/bootloader.rb 
# result on my workstation: yast2-bootloader-3.1.128-1.14.x86_64
