Emails displaying content from other emails

[jry]

Weird problem going on here with the Sugar email client.

For example, an email might show this in an email account inbox (listing):

From: John Doe Subject: Regarding my credit card

But upon clicking the email to open it, it then shows a different email:

From: Joseph Baker
Subject: Your car service
Content: Text about car service

This is happening to about 10% of received mail. I'm guessing Sugar is saving a pointer or caching incorrectly.

Any ideas about this strange problem?

[EDIT]
- Sugar: 5.2.0f
- Also thought it might be relevant that I have multiple monitored folders (e.g. INBOX, STORED)

OK ... what's your stack?

Have you customised the email client in any way?

FYI: The mail client is fairly buggy

A number of issues have been addressed in the mail clinet since patch f ... try upgrading to j and see if that fixes the issue.
