I tested it with Emacs 25.1 RC1, but it might have been fixed in an
earlier release.

Michael said he has found the git commit in which this bug was fixed:

     c46c57b, Stefan Monnier <monnier@iro.umontreal.ca>

Which was committed 3 years ago, so Emacs 24.4 should have it, but I
would suggest installing Emacs 24.5 (the latest stable release) instead.

Cheers,
Nico
