Comment 7 for bug 1051718

This problem has to do with a buggy version of "Dee".
That problem got solved in 12.10, but not in 12.04.

With that bug, you are not able to develop your lenses and scopes for ubuntu unity with Python3 :(
I've already ported all the code to Python3. So to fix that, I would have to backport , or offer an older version.

I've gotta take a look into backporting in the holidays, I hope.
