Favorites button causing break on OSX

[sloumdrone]

A report from @cpj has come in stating that the favorites button causes a break on OSX. I do not currently have many other details.

That said, my first thought is that the break is caused by lack of support in the OSX version of Python Tk for the following: import tkinter.simpledialog

It is possible that this is required as an add on either through pip or through some kind of update to the underlying C headers that Tk uses. I good check for this might be to see if file save works on OSX. If it does then there may be another cause as savedialog is another submodule to tinter....
