Bug#560073: icedove (64-bit) + dovecot (32-bit); communication sometimes breaks down

[Mario Nigrovic]

Package: icedove
Version: 2.0.0.22-0lenny1
Severity: normal

For several months now (but since before I started using iceweasel from sid), I've noticed that, from my 64-bit icedove client only, sometimes communications between icedove and dovecot will stop.  Icedove will show new messages in the folder (and I have procmail delivering mail to many separate folders, which icedove watches for new messages), but when I click on the folder, the new messages cannot be displayed (none are even shown).  Furthermore, old messages in the same folder cannot be displayed, although the index does continue to list them.

I think this problem also shows up when I search messages, because sometimes searches miss messages I know are there.

I have one (32-bit) dovecot IMAP server and multiple clients; however, I've only seen the probem from the 64-bit version of the client.

This bug sounds similar to 515569, which is also from a 64-bit client, so perhaps this is a duplication.

My personal suspicion is that this is a dovecot issue, since I recall it starting after an upgrade to that package, but I don't recall whether that update also brought a new version of icedove and since the problem only shows up from the 64-bit client, I figured it's worth reporting here.

I'm happy to provide any debugging assistance necessary.
