 It is possible for someone with the unfiltered_upload capability to upload
 attachments with unknown extensions. There is a bug which generates the
 filename in that instance, which results in a file called test.phps to be
 uploades as testphps..phps.

 This is caused by the extension guesing code leaving the . before the
 extension, which is added again later on, making a few replaces fail.
