Comment 3 for bug 1189190

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner.

The good news is that this was fixed in the corresponding Debian report, and I've verified that the manpage is installed and work as expected in mtpaint 3.40-2.2 on Ubuntu 16.04.
