I tried your patch and I can confirm that it works. I can now run an application directly in a Python interpreter:
$ python bin/project_name
A step towards more IDE-freedom :) Over the next couple of days I'll see how it plays with PyDev and see if I can make some new branch with better integration. What is the desired workflow - branching trunk on lp:quickly or branching lp:ubuntu/quickly?
P.S. - do you know why I had to manually input the path to the file that is to be patched? I was inside the quickly project directory (with the README, bin/, data/ ... folders), issued:
$ wget https://bugs.launchpad.net/quickly/+bug/976817/+attachment/3069953/+files/976817-schemas.patch
$ patch -p1 < 976817-schemas.patch
and it always asked me to manually enter the file to patch, saying "can't find file to patch at input line 4". After I enter the same path that is stated in the patch it works.
