In thunderbird 2, when you right-clicked on a message, one of the menu items that appeared was "Move to <folder> again", where <folder> was whatever folder you last moved a message to. This was extremely useful. In thunderbird 3, the menu item just says "Move again", which is utterly useless, since there's no way of knowing for certain what folder it will move things to unless you just did it a second ago, which certainly isn't always the case. This is a serious regression.
We find this bug has been already fixed upstream (https://bugzilla.mozilla.org/show_bug.cgi?id=473168). Red Hat will continue to track the issue in the centralized upstream bug tracker, and will take care this patch will get into our release. Thank you for the bug report.
