As I see there is already a duplicate for this bug:

Similar crash happens on my system as well after the latest update.
For me it's happening only on 'Main Repository (OSS)' and 'Main Update
Repository' when I select the repositories under View drop-down list.

This is what's happening on my system:
Select 'Main Repository (OSS)', click on any checkbox of any either installed
or not installed package, system hangs with high CPU load for 5 sec then crash.
Select 'Main Update Repository', click on any checkbox of any either installed
or not installed package and it crashes instantly.

Obviously I've several additional repo added but I disabled them, also
reinstalled YaST2.

I try to find out what's going on and I attach several result although not sure
if my research would be worthwhile in this case.
