Could not resolve rosdep key 'rospkg'

edit

Similar to this thread but the solution there (replace rosdep files) does not change the result.

$ bloom-release --ros-distro groovy rqt_common_plugins groovy

The version of source used is available here.

What is wrong? Also, is there anything I should do when re-running bloom-release (since it failed this time. Looks like nothing is pushed yet to the release repository)? Thank you!

python-bloom 0.3.3-1, python-rospkg 1.0.20-1 on Ubuntu Quantal.
