Thanks for the bug report. I have fixed this problem here
(https://github.com/galaxyproject/planemo/commit/a32d082eeee0a6b856d8d15c9619c97549230a17)
and released a new version of planemo (0.13.0) with fix. Hopefully you
will get a better error message after the upgrade if there is still a
configuration issue.
