Django imports problem -- and fix?

[Ram]

It seems this line 

hiddenimports = [django_dottedstring_imports(root_dir)

                 for root_dir in django_root_dirs]

in hooks-django.py can call django_dottedstring_imports with an empty root_dir, which causes the os.path.basename to crash pyinstaller. 

Since I was not using django, I just replaced the above line with 

hiddenimports = [None]

and it was able to generate my EXE file. Perhaps there is a better way to fix this bug?

Thanks,

--Ram.
