portupgrade-2.2.2_1,2 corrupts portsdb

[Bartosz Fabianowski]

Hi all

As part of the daily portupgrade run on my 6-STABLE box, I upgraded 
sysutils/portupgrade to version 2.2.2_1,2 yesterday. Today, when I tried 
running this version, I got the following error message:

%portupgrade -ai

Apparently, the portsdb database is corrupted somehow, gets rebuilt but 
is still not acceptable. According to the error message, a key named 
"categories" seems to be missing from some table. Has anyone else 
experience this? Is there a workaround or a fix?
