YaST2 partitioner crashes when selecting the logical volume "lvol0" in the
devide tree under <pc name>/Volume management/vg1/lvol0
The error message complains about a method "stripes_size" (which should be
'stripe_size').

The logical volume "lvol0" was set up previously using 
 lvcreate --type raid5 --size 4000G --stripesize 512k vg1

reproducable using current tumbleweed (same using yast-storage.ng from
Yast-Head repository
