Hellow Everybody

I tried Making LVM Partition on eSATA HDD
Making LVM Partition was completed

But I got error dialog "incompatible character encodings ASCII-8BIT and UTF-8
in /usr/share/YaST2/lib//y2storage/callbacks/commit.rb"

Do I have any mistake?
Can I Fix this problem?

Sorry my poor English
