During glass_watch, when a file is renamed, watch stops with an error

[kkellydesign]

To create a new file I typically just copy a similar file, then rename it. that throws an error and stops glass watch from running:

Exception in thread Thread-1:
Traceback (most recent call last):

IOError: [Errno 2] No such file or directory: 'templates/projects 2.html'

Where 'projects 2.html' is the default name of a duplicated file before I rename it. I've let a file sit for a while to make sure that I didn't just confuse it while it was trying to upload, but that's not the case. Even if I wait several seconds for the upload to complete before renaming it, I still get the error.
