To clarify Jim's comment, I failed to properly escape the . in the filename -- without being escaped the . means "a character". This character could be anything, and is probably a "." but could be a space, or any other character.

I strongly agree with Jim's advice to make URIs lowercase. The HTTP spec allows to domains to (www.example.com) to be delivered in any case, so any matching on domains should use the [NC] flag, however the path part of a URL is case sensitive. To avoid confusion, go with lower-case.
