When I delete one of the duplicate messages, both messages are removed, but an empty message dated 01-01-1970 remains in the shared inbox. The trash folder now contains both an empty message and one of the duplicate messages that was deleted. I have to move this message back to the inbox , because it is not there anymore. Reproducible: Always

Related to Bug 136049?

To comment#1: Maybe, i noticed this after a DST change and I have my mailboxes on a FAT32 partition. Symptoms are similar to bug 312519. I opened the "Local Folders\Inbox" file in vim. I saw that the messages are there twice with the same Message-ID. It is possible that these problems started after creating some new filters on deferred accounts. I am hesitating to try to reproduce the problem, because I don't want to loose my mail.

I deleted the .msf files of my inbox and trash folder. They were out of sync with the corresponding mail files. The duplicate messages have now disappeared.
