KfW 3.2.2 and plink on Vista

[petesea@bigfoot.com]

I have a Kerberos enabled version of PuTTY which works fine on XP using 
both KfW 3.1.0 and 3.2.2.   It also works fine on Vista using KfW 3.1.0.

But on Vista using KfW 3.2.2, plink triggers a Vista error popup with the 
following detailed info.

Is this a problem with KfW?  Or plink?  Or Vista?
