Status: RESOLVED DUPLICATE of bug 341568

(Thunderbird :: Mail Window Front End, defect)

Description

[Sergey Fukanchik]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11
Build Identifier: version 3 alpha 1 (20070322)

Sevral days ago i noticed that some messages in message list have blank titles (see attached screenshot). Tooltips aren't shown too.

Reproducible: Always

Steps to Reproduce:
If message is shown without subject in list it's show always - even after thunderbird restart.
Actual Results:  
Some messages shown with blank subject in message list pane of thunderbird.

Expected Results:  
I expect to see same subject text that is shown at the header of message pane.

Screenshot is taken from latest build which i made after when three hours ago i made cvs update.

All such messages have subject that is Encoded-Word. Here are few examples of such  subjects:

Subject: [Comm] =?koi8-r?b?4sXT0NLPwtXEztnKINPPziA9KQ==?=
Subject: [Comm] =?koi8-r?b?c3dmIC0+IHZpZGVvLCDLz83VIM/OzyDO1dbOzw==?=

opposite, here are several Encoded-Word subjects which are shown normally:
Subject: [Comm] =?windows-1251?b?0e/o8e7qIPDl7+7n6PLg8Ojl4g==?=
Subject: [Comm] =?koi8-r?b?IPrB0NXTyyBOYXVEb2M=?=
Subject: [Comm] =?koi8-r?b?TGlsbyAmIFNvZnRSYWlkIDEg7sUgx9LV2snU09Eg0yDX?=
 =?koi8-r?b?yc7Uz9cgOig=?=

but of course i'm not sure that it's a subject text is what causes this bug.

BTW, all those messages are shown correctly in thunderbird "version 1.5.0.10 (20070221)", which i downloaded from mozilla.org. Both apps share the same database.

Do the messages that don't display correctly contain multiple Subject: headers?

Attachment: Source of message which is shown incorrectly in message list pane.

No, they contain single Subject: header. Attaching source of one such message.

Please note: attached file is result of copy/paste of message source into another editor, so it's probably have wrong kind of line endings (CR/LF).
