imagecache_external_generate_path('http://example.com/this/does/not/exist.png') returns the nonsensical "http://localhost/sites/default/files", which is not an image. It should thrown an exception instead, or return an empty string, both of which would make more sense than "http://localhost/sites/default/files".
call imagecache_external_generate_path('http://example.com/this/does/not/exist.png')
Throw an exception or return an empty string if the source file does not exist.

Actually this is a PBKAC, just realized this is already returning FALSE, which is good.
