You know ResultSetManager is deprecated / not recommended and scheduled 
for deletion, right? Guess you're getting this from the catalyst book, 
I'd recommend seeing the errata page which covers this 
(http://dev.catalyst.perl.org/wiki/thebookerrata)

This looks to me like the perl 5.10.0 attributes bug, which causes 
'Unknown error' rather than a useful message.

Can you try a different version of perl to see if it becomes more helpful?
