Ok, I tried to strip down my schema so that you can have a look at it:

http://www.funkreich.de/files/dbic_wreck.tar.gz

runme.pl fails on my system - The call to custom_method() tries to use the
ResultSource that is created in Wreck::Schema::User although it should just use
the "normal" relationship called relation_a (notice the "I AM NOT SUPPOSED TO BE
CALLED" string in the output). The "prefetch" parameter in custom_method seems
to somehow have to do with this.

What I find most interesting is the fact that the name given to
->register_source in Wreck::Schema::User has an influence on the whole case.
Try changing it from "MyResultSource" to "UserMutual" and suddenly everything
works as intended.

What kind of magic is going on there under the hood? :)
