After talking with Keisuke at the summit it was found that:
the code I was using was NOT correctly escaping the file or folder path.
this was due to a failed copy/paste of some of Keisuke's code (LEP_Escape from
one of his demos).
Replacing the broken code with the correct code resolved the issue.
Thanks for everyone who tried to help
and special thanks to Keisuke!
