458610 - More unread messages than total messages in thread (message count)

Status: RESOLVED DUPLICATE of bug 1740312

(MailNews Core :: Networking: NNTP, defect)

Description

[Nelson Bolyard (seldom reads bugmail)]

Attachment: screen shot

SM trunk nightly Gecko/20080930003201 

Viewing a mozilla newsgroup, viewing threads with unread, the message list
pane, shows a thread that has a total of 3 messages, all in read state
(none unread), yet it claims that the number of unread messages in that 
thread is *7*.  

Rebuilding the summary file with the button in the newsgroup properties
dialog has no effect on this.  Does it even work?  How could it fail?

AFAIK, SM 1.x did not do this.  This is a regression.

Why doesn't the "rebuild summary file" fix this? 
Is it simply not rebuilding the summary file?

Not blocking release on this, it apparently isn't happening often enough that attract more feedback, and there's nothing lost, it's just a wrong display in the UI. We'd surely like a fix, but we'd not put a release on hold for it.

Maybe jcranmer knows of other bugs relating to thread counts.

With bug 520582 being one of the latest fixes in that area, I couldn't reproduce any issues of this bug with ESR 128. Otherwise, there's still one recent report in bug 1740312, so let's continue there if necessary.
