Development versions of mu between 1.7.18 and 1.7.25 (only 1.7.23 was ever
packaged in Gentoo) have a bug causing mail file names to sometimes get mangled
after moving messages between directories. Symptoms include unread messages
never being marked as read.
Affected messages have the ':2,' flag appended multiple times. Using the following commands, users can remove the extra flags.
