I`ve installed that awesome plugin Advancednewfile but I can’t run it due to rfind() error in python from Sublime Console.

File “./sublime_plugin.py”, line 350, in run_
File “./AdvancedNewFile.py”, line 10, in run
File “./AdvancedNewFile.py”, line 18, in get_root
File “/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/posixpath.py”, line 119, in dirname
i = p.rfind(’/’) + 1
AttributeError: ‘NoneType’ object has no attribute ‘rfind’

Can you help me out with this?
