Invalid package manifest of qt-ros when invoking catkin_make [closed]

edit

On my PC where I was 'always' able to build my workspace I recently (maybe since some update) ran into the following problem when invoking catkin_make

  Invalid package manifest
  /opt/ros/hydro/lib/python2.7/dist-packages/qt_create/templates/qt-ros/package.xml":
  Package name "%(package)s does not follow naming conventions

I use ros hydro on ubuntu 12.04 64 Bit. Full catkin_make log:
