Looking at the recent changes in indicator-messages, I believe this is related either to https://code.launchpad.net/~ted/indicator-messages/lp1385331-unescape-message-ids/+merge/250235 or https://code.launchpad.net/~larsu/indicator-messages/lp1386584/+merge/240773. The latter has some complaints about the "Clear all" button in the MP discussion.
