457097 - [Regression] "Re: " not shown in threadpane for some messages

Status: RESOLVED DUPLICATE of bug 287271

(MailNews Core :: Database, defect, P3)

Description

[Ben Bucksch (:BenB)]

Attachment: Missing Re:

Regression

Quite frequently, the subject in the threadpane does not show the "Re: ". I get several messages from a thread with the same subject without Re:, which makes them all look like thread starters.

At the same time, other messages from the same thread may show Re:, depending on situation. I think this bug appears for new messages only. When I restart Mailnews, the messages show the correct subject (with Re:). Opening another folder and coming back is not sufficient to make the Re:s show.

This is observed with build 2008-09-03. I will try a newer one once I have it compiled.

this has been happening for a very long time, but it's very sporadic and hard to reproduce.

Comment 3

[Ben Bucksch (:BenB)]

I didn't see it in the build from mid-July.
I see it fairly frequently. Esp. for new mail, when I open the folder for the first time after launch.

I remember debugging it a year ago and not getting anywhere...

Comment 5

That's strange. I'm pretty sure I have not ever seen this before a month or so ago.

Either it's a different bug, or something triggering it now, or some environmental factor, e.g. a corrupted .msf file, lots of restarts etc..
I see this in many folders, though. I have much more restarts and crashes recently, but had a few before, too.
Or maybe it's just that I used TB2 until recently and this is a TB3 regression? But still, I don't think I saw this in my 2008-07-21 build.

Either way, this is very prominent / high profile, at least for me. I see this a lot, and it's very confusing. I think this is a TB3 blocker.

Your image suggests you're not using threaded view?
Is the missing Re: stable, i.e. does it happen for the (exact) same messages after a program restart? Does changing the view/thread mode/folder/sort help?
Do you see a simple pattern in those messages, e.g. same (type of) encoding in subject/body or same (type of) content-type?

Correct.

Currently, it seems to be, given that I have messages form the last days in that folder which show the problem, although I restarted yesterday.

I think I did see it, though, that a restart fixed it.

I also think that it applies only to some messages, e.g. the first messages that appear in the folder after TB start. Msgs coming in later would be fine - I remember seeing something like that.

Note that even right now, some messages have the "Re:".

> Does changing the view/thread mode/folder/sort help?

No. I am attaching a screenshot of threaded mode. It shows that even there, most msgs have no "Re:", but some do - the same msgs as in unthreaded mode.

No.

I just got this in threaded mode, for two mails to the tb3-drivers list, though I don't recall seeing it ever before. Rebuilding the index fixed it. (I've saved the bad .msf in case someone wants thinks it would be useful to look at.)

taking, but STR would be very helpful.
