Description of problem: When a message is moved between IMAP folders (on one server or between two servers) and the destination server disconnects for some reason during the transfer evolution removes the email from source folder anyway. This is severe dataloss bug. Version-Release number of selected component (if applicable): Happens in all evolution releases since at least FC6 till rawhide. (Btw if you combine evolution with the dovecot in rawhide which crashes frequently on large Maildirs, you can reproduce this very easily, but it is not dependent on the exact IMAP server, it will happen with different servers on network errors etc...)

Moving messages on an IMAP server actually means marking the message for deletion on the source folder and copying it to the destination folder. In the times this has happened to me, I can usually find the message in my Trash folder and undelete it from there. It then shows up again in the source directory. Lowering the severity.
Yes, but if you have filters which move the messages automatically you might not notice that some message was deleted and didn't appear on destination. So you don't know that you should look for it in trash.
Moving this upstream where I'll continue to track the issue. Please see [1] for further updates. [1] http://bugzilla.gnome.org/show_bug.cgi?id=512798
