[Ros-release] base_name failures of dry debbuilds

Hi Everyone,

I just wanted to let you know that we've had some spurrious failures of the
dry debbuilds in the last few days. The urls were missing a variable for
the template which was creating the "base_name" exception which I'm sure
many of you saw. It's been resolved now. If you see this error again
please let me know. I thought it was a chroot issue yesterday, but found it
was just a missing substitution argument with a terrible exception.
