Comment # 6 on bug 896479 from Wolfgang Bauer

I experienced a similar crash upto 13.2 Beta1, but for me it was the Kerberos
plugin:

But after upgrading the system to latest Factory it works fine now.

As I don't see anything wrong neither in SmbHash.pm line 14 nor Symbol.pm line
81 (not even in the 13.2 Beta1 packages), this might have been a perl bug. And
indeed downgrading perl to the packges in 13.2 Beta1 makes it crash again.
It seems that it fails to parse the version number if the current locale
doesn't use '.' as decimal point.
So running YaST with english locale helps as well (I just tried) and might be
the difference between your user account and root.
E.g. with "kdesu LANG=C /sbin/yast2".
