378100 - search/message filter fails when subject has line wrap/carriage return

Status: RESOLVED DUPLICATE of bug 124641

(Thunderbird :: General, defect)

Description

[Keith S.]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3
Build Identifier: version 2.0.0.0 (20070326)

I've received some emails where trying to filter based on the subject contents is failing. For instance, if I try to query for "Customer Milestones", it fails to find it, even though I can see it quite clearly in the subject line.

Further examination shows that when the message was downloaded, the subject line was wrapped, like so (directly from the folder file on the OS):

Subject: Status: Major ...[removed for privacy reasons]... Customer
 Milestones last week

Nothing on the new line can be picked up in the search box, or a mail filter.

It is not clear whether Thunderbird is inserting that line feed or not. I have some emails with longer subject lines that do NOT wrap, and only a few that do. Some (that wrap) were sent by Netscape 7.1, some by Thunderbird 1.5. In some cases, the very same message sent by TB 1.5 wrapped in one case, but did not wrap when a reply was sent (or vice versa).

Reproducible: Sometimes

Steps to Reproduce:
1. Send an email with a long subject line to yourself
2a. Fetch the message, then try to search for a word at the end of the subject line; OR
2b. Look at downloaded message contents to see if the subject wrapped (there's always a space on the next line, so you can regexp search ^Subject:.*\n<space>

Agreed. Sorry, I searched on TB as the product; didn't think to also search on Core.
