279820 - new mail reported, but there is no new (or even unread) mail in any folder

Status: RESOLVED DUPLICATE of bug 253341

(Thunderbird :: Mail Window Front End, defect)

Description

[Sam Halliday]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-gb) AppleWebKit/125.5.5 (KHTML, like Gecko) Safari/125.12
Build Identifier: 

in OS X (btw, bugzilla will not let me enter this bug if i have OSX as the OS version), having Thunderbird 
check for new mail every 10 mins or so in an IMAP account results in the dock icon *sometimes* 
declaring 2 new mails. a check of my inboxes will reveal no new messages.

once this happens in a session, it will continue to do so every time TBird checks for new mail. it is very 
annoying and i must quit and come back again.

Reproducible: Sometimes

Steps to Reproduce:
1. leave TBird running (even minimised)
2. wait for auto fetch to kick in... the bug happenning is sporadic
Actual Results:  
2 new mails reported

Expected Results:  
not reported any new mail (i didn't have any!)

i also have an RSS account (and local folders) and an empty (not subscribed to anything) news account. 
but their fetch times do not coincide with the IMAP checking, so i reckon its just the IMAP account 
causing this.
