[Catalyst] Can't call method "can" on an undefined value in CPAS::DBIC

[Richard Jones]

I've been away from Catalyst development for some time to concentrate on 
optimising my database tables. Now I have the new schema I'm getting the 
following error when trying to start the server:

Can't call method "can" on an undefined value at 
/usr/local/share/perl/5.8.7/Catalyst/Plugin/Authentication/Store/DBIC.pm 
line 98. The module in question is at version 0.09.

I'm using DBIx::Class::Schema::Loader to generate the schema 
automatically, but can't seem to make the error go away even when 
reverting to the original schema. Something else has probably changed in 
the meantime which I have overlooked. Does this error mean anything to 
anyone?
