I would classify this as a MacRuby bug.

  - 2.0.0
  - 1.9.3
  - 1.9.2
  - ruby-head
  - 1.8.7
  - jruby-19mode
  - jruby-head
  - jruby-18mode
  - rbx-19mode
  - rbx-18mode
  - ree

This regex has worked for the better part of ~8 years on most other Rubies, and whenever I commit a change, Travis CI now runs against the above versions.

This is a bug in MacRuby. It only happens when you use /x regular expressions. It sees the # and assumes it's a comment and clears the rest of the line. This can be fixed by escaping the #.

This will be resolved permanently in MIME::Types 2.0 because the custom data format will be replaced with a YAML format, as noted under #37.
