329665 - Thread cannot be expanded if "unread" filter is active and new mail arrived

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

Description

[Michael Wild]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051111 Firefox/1.5
Build Identifier: version 1.5 (20051201)

When filtering mail with "unread" and sorting by thread, it is not possible to expand a thread if new mail arrives belonging to the thread while reading the "parent" message. Clicking the expander just results in the symbol + changing to -, but the thread does not unfold.
This behaviour can easily be reproduced (see below).

Reproducible: Always

Steps to Reproduce:
1. In you inbox choose as filter "unread" and apply "View|Sort by|Threaded"
2. Write an email to yourself and click the "Get Mail" button until it arrives.
3. Reply to it, not changing the subject.
4. Again, wait until you receive it (if necessary by pushing "Get Mail").
5. Now you see, that the original mail is marked red, but the expander appears und the underline in the subject indicates that the thread has unread children.
6. Try to click the expander. Nothing happens, except that the symbol of the expander changes from + to - and the underline vanishes.
7. Do be able to read the new message, either change the folder and come back, or switch the "unread" filter off (and perhaps back on).

Actual Results:  
The thread does not expand.

Expected Results:  
The thread should expand and the unread message should become visible.

Just want to confirm that this occurs on Windows as well.

I can confirm this on Linux: Thunderbird 1.5.0.8 on Ubuntu 6.10 and Scientific Linux 4.3 both show this behaviour. I can't comment on Windows, I'm afraid, so it might be a GTK-specific bug. It's a very annoying behaviour, though, since it means you have to continually turn the Unread filter on and off to follow the development of a thread in the Unread view.

Andy, Keenan, Michael, do you see this in newest releases of version 2?

It now works for me, using Thunderbird 2.0.0.14 (20080227) from Ubuntu Gutsy.
