Exception while executing SCM command.

I'm new to maven, so please excuse if this is my fault, but when something throws me an exception I consider there's a bug. So here you go. I'm trying to checkout my project using maven scm:checkout and this is what I got:

build:start:

scm:find-connection:
[echo] Using connection: scm:cvs:pserver:cvsrep@(obscured):/export1/cvsrep/cibos:Factorial

scm:checkout:
