AttributeError: 'NoneType' object has no attribute 'startswith'

I'm missing something here. I am running Sublime Text 2 and the debugger on my Mac locally with my local set of code for adding breakpoints. I open the page in the browser remotely on a dev server. For some reason, my dev server wants to force the xdebug.keyid to "root", but it seems to be communicating with the debugger just fine. Quality time with Google tells me that it may be looking for (and not finding) some file, but what?

When I start the debugger and refresh my page, I get the following:

Traceback (most recent call last): File "./Xdebug.py", line 332, in gui_callback File "./Xdebug.py", line 209, in breakpoint_init File "./Xdebug.py", line 222, in uri File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/posixpath.py", line 357, in realpath if isabs(filename): File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/posixpath.py", line 52, in isabs return s.startswith('/') AttributeError: 'NoneType' object has no attribute 'startswith'
