[Templates] Bug accessing lists with a single element, introduced between version 2.14 and 2.19

[Knut-Olav Hoven]

I am using Ubuntu Feisty with libtemplate-perl 2.14-1 on my development 
machine and Ubuntu Gutzy with libtemplate-perl 2.19-1 on my production 
machine (test now, soon production).

I have an object of type "User" with a "cards()"-method that returns a list 
(not an array ref, but a list) of cards, with type "Card", associated with a 
user. The user object is accessed through the "user" variable in my 
templates.

When the "cards()" method returns a single element I get an error telling me 
that there is no method called "Card::size".

This bug only hits in when there is a single card associated with the user, 
not with 0 or 2 or more cards.


Example usage in templates:
[% IF user.cards %]
	[% user.cards.size %] cards
[% END %]


I have also tried to call it like this without any luck:
[% user.cards.list.size %]


Just for the record, I am using Catalyst and the TTSite view (0.24 vs. 0.25), 
but I don't think it has anything to do with this because I call 
the "cards()"-method from the templates, regardless of how Catalyst is 
setting the "user" variable for use by Template Toolkit.
