333830 - Remember Last Message + switching to View:All folder from View:X => garbled (non-ASCII) message

Status: RESOLVED INCOMPLETE

(Thunderbird :: Mail Window Front End, defect)

Description

[Yannick Majoros]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)
Build Identifier: version 1.5 (20051201)

I noticed that sometimes, the preview pane displayed garbage characters instead of international characters. It looks typically as UTF-8 chars displayed on ISO-8859 terminal: 'é' instead of 'é', ...

This happens when you go from a specific view to another. I have been trying to reproduce this for a while, and now I know a specific situation where it does it all the time. The problem is that, if you select another message in your inbox, then the problematic one again, it displays correctly... Unless you go to the specific steps which lead to this bug.

Reproducible: Always

Steps to Reproduce:
1. Go to your inbox and select a ISO-8859-1 encoded message.
2. Go to any RSS subscription which has a couple of unread messages. 
3. Select View->Unread (important step, won't work if you don't do that).
4. Select any message in any encoding (doesn't matter to reproduce this bug).
5. Select your inbox.

... and the message display is incorrect (2-bytes garbage instead of international characters).

For some message, it just won't display if you try this.

Actual Results:  
Example of bad message display:

Yannick,

Pourrais-tu envoyer un message encodé utf8  à l'adresse [e-mail]
?

merci,

Louis

Comment 1

[Yannick Majoros]

It seems that you don't need a RSS subscription for this. You could replace step 2 with a message in any other box, as long as you do step 3.

Comment 2

[Yannick Majoros]

Same for step 1: you don't even need to select a 8859-1 encoded message, it seems it work with a UTF-8 encoded one too. I made some tests, and the message is either displayed with garbage, either not displayed at all.

Actually, this bug seems to be easy to summarize: going to some mailbox and viewing unread messages loses encoding of message displayed when you go to another mailbox.

Comment 3

[Mike Cowperthwaite]

Looks like the same problem as bug 315957 -- Yannick Majoros, if you agree, please mark this bug as a dupe of that one.

Comment 4

[Yannick Majoros]

No, it doesn't seem to be like bug 315957 . I tried to reproduce the steps in 315957 without seeing the described problems. Showing/hiding the preview pane doesn't seem to do anything here.

I don't know if it helps, but html emails which use html character entities instead of 8-bit or multibyte charsets don't give this problem.

Comment 5

[Yannick Majoros]

Could someone actually try the described bug? I can reproduce it 100% of the time on my setup, now.

Comment 6

[David :Bienvenu]

Yannick, have you tried a recent trunk or 2.0 (aka 1.8) nightly build?

ftp://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/latest-mozilla1.8

Comment 7

[Yannick Majoros]

Just tried version 2 alpha 1 (20060501), seems to be resolved. I could reproduce the bug before installation of the new version, I can't anymore.

Thank you!

Comment 8

[Yannick Majoros]

Still unresolved :-(

Today, I saw the same old behavior, and I tried to reproduce this bug... The bug showed up 100% of the time :-( Either I was too quick with my previous testing of version 2 alpha 1 (20060501), or there is an additional unkonown condition to reproduce this bug.

Can someone try to reproduce it? I can give more info if the procedure is not clear enough.

Comment 9

[Yannick Majoros]

Hello,

Can someone at least _try_ to reproduce it and give some feedback? It is a real problem for non-english speakers :-(

Comment 10

[Wayne Mery (:wsmwk)]

Yannick, does it happen with trunk ? http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/latest-trunk/

Comment 11

[Mike Cowperthwaite]

I've figured out how to reproduce this bug, using the test message above.
It's necessary to have "Remember last message in folder" selected.  I should have figured that out from the steps-to-reproduce, I guess.

Steps to Reproduce:
1) Set "Remember last message in folder" option.
2) Select a message somewhere that has a non-ASCII charset
3) Be sure the mailview for this folder is "All"
4) Select a different folder; if the mailview in that folder is All, then set it to be something else -- Unread, Tag=X, whatever.
5) Re-select the original message folder

Actual results:
5) message appears with characters garbled in some way or other.

I'm not sure what the actual garblement is -- it seems to be a dump-as-Win1252 of the UTF-8 bytes of the message, but I'm really not sure.

Also xref bug 278971.

Comment 15

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

Yannick, Mike, does this still occur in the latest 2.0.0.x or trunk nightlies?
