292458 - thunderbird (several versions) freezes with 100%cpu with duplicate message-id message id ids

Status: RESOLVED WORKSFORME

(Thunderbird :: General, defect)

Description

[Meat Popsicle]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3
Build Identifier: Debian thunderbird: version 1.0.2 (20050331) and others (recent)

thunderbird freezes with 100% cpu load when a local folder contains several
messages with the same message-id but different contents. The bug may be
triggered by 10-15 messages with the same id in a folder that contains 100+
other messages.

Reproducible: Always

Steps to Reproduce:
1. create a set of messages of which 10 have the same id (by editing them)
2. feed messages to test email account via MTA (f.ex. using formail)
3. open thunderbird on that account and get all the messages, save them to a
dedicated folder (assume they come from a mailing list)
4. close and reopen thunderbird. The bug should appear (at the latest when
opening the relevant mailbox folder)

Actual Results:  
100% cpu load and no reaction from thunderbird

problem was reported by several users on different platforms. It was caused by a
broken email system that sent messages with the same ids to a mailing list over
about two weeks.

Expected Results:  
normal operation (open thunderbird)

Thx for the sample messages. This works fine with trunk builds. The fix will be
in 1.1.
