harpia doesn't start any OpenCV program

Binary package hint: harpia

Harpia is not starting any OpenCV program one creates in it. So it is not usable at all.
When I started it from the Terminal it gave me the following messages:

~$ harpia
/usr/lib/python2.6/sets.py:85: DeprecationWarning: functions overriding warnings.showwarning() must support the 'line' argument
  stacklevel=2)
/usr/lib/python2.6/dist-packages/harpia/amara/bindery.py:4: DeprecationWarning: the sets module is deprecated
