Yast bootloader module fail

Dear friends,

on latest Tumbleweed, Yast bootloader module fails to start. Here is the output:
Internal error. Please report a bug report with logs.
Details: undefined local variable or method extended' for #<Bootloader::Stage1:0x102bb4b0> Caller: /usr/share/YaST2/lib/bootloader/stage1.rb:172:in available_partitions’

Here is the output of parted -l:

Model: ATA SAMSUNG SP1233N (scsi)
Disk /dev/sda: 120GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

7 2592MB 45.5GB 43.0GB logical ext4 type=83

How can I fix it?
Thank you!

It should be fixed. You must update to 20160504.

No, the problem persists even with the latest updates.

I would make a bug report. The sooner it’s reported the sooner it’ll get fixed.

I downloaded build 505 today. I did a fresh install and the ruby file errors no longer appear.

It appears to be already on bugzilla, 978691 – YaST2 bootloader crash with undefined local variable or method 'extended'
Just added my logs there.

Clean install of Tumbleweed 20160505 failed here with a similar error message (as did all TW’s later than 20160430). Added as comment to bugzilla.

Bug fixed: TW20150514 installed normally.
