**Short description of error**
Mifth Tools shows an error while trying to perform DrawClones operation.
**Exact steps for others to reproduce the error**
1. Enable Mifth Tools addon. If you don't have it, download it from here: https://github.com/mifth/mifthtools/archive/master.zip
2. Create an empty scene, add a plane and a cube and move the cube away so it will be possible to draw on a plane.
3. Select the cube and press PickObjects
4. Select the plane, press DrawClones and try to paint on a plane
If you reproduce these steps in 2.76, everything will work as expected and you will get some cubes on a plane. In 2.77 addon outputs an error and does nothing. This addon is extremely useful and it would help a lot to know whether this error is expected in new version of Blender or caused by a bug somewhere. The same error occurs on different computers so this is not caused by a particular machine or an addon distributive.
I don't expect Blender developers to act as an addon tech support, but I want to make sure that error is expected and not caused by a bug in Blender itself (probably due to the recent changes in Python or something like that) so it will be possible to contact an author of the addon for further investigation.
