One of the reasons that pan was uploaded to unstable is to find and fix any existing bugs in due time.

It is a pain, yes. But for some packages there is no guarantee for an automatic upgrade path, so you'll have to live with it. Note that this is is an upstream issue so all users of all distros suffer from it. > I hope the version of Pan is removed by the end of the day! It won't, I hope. The old pan is not supported by upstream and although more stable than the new one, has plenty of annoying issues and bugs, which Søren Boll Overgaard has been fixing through the years with passion and love. It is inappropriate to insist to continue this nightmare for him throughout Etch's timeframe.
