Comment # 3 on bug 914812 from Stefan Schubert

I think, that call:
2015-01-25 11:15:23 <1> 192.168.9.37(2827) [Interpreter]
clients/inst_autosetup.rb:290 Calling YaST client bootloader_auto
2015-01-25 11:15:23 <1> 192.168.9.37(2827) [Ruby] yast/wfm.rb:181 Call client
/mounts/mp_0001/usr/share/YaST2/clients/bootloader_auto.rb
2015-01-25 11:15:23 <1> 192.168.9.37(2827) [Ruby]
installation/auto_client.rb:36 Called Bootloader::AutoClient.run with Import
and params {}

BTW. I have tested this autoinst.xml file (reported in first comment) and 13.2.
I have not had any problem :-)
