Comment 2 for bug 615543

Still a problem under Maverick. It turns out it's exactly half of my messages: I've realised that I get a duplicate notification for one seemingly-random old message for every time I delete a message from my inbox.

Since I use alpine (with the infamous non-Gnu maildir patch) to delete messages, and this news gets to Google through offlineimap, I guess there are a few places where the trouble/incompatibility could be happening.

Maybe for some reason, some message ids are being revised?
