Code review comment for ~zioproto/ubuntu/+source/cinder:stable/liberty

I am building this package as follows:
sbuild-liberty -A -d trusty-amd64 ../build-area/cinder_7.0.2-0ubuntu2.dsc

The dsc file looks good.

I have no idea why in the final deb package, the 'Depends:' section of the package control file is broken. There are some packages that are mentioned with an extra dash (-), like for example 'python-novaclient-'. This makes the package impossible to install. I paste here the control file:
