305113 - apparent looping when loading message with many attachments from IMAP server

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

Description

[Jim Gibbons]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Thuderbird version 1.0.2 (20050317)

I received an e-mail with 73 attached JPG files, each of which was a little
under 100K.  The mail is stored on a Kerio Mail Server with an IMAP interface. 
Thunderbird seemed to be processing this in an unending loop.  I was able to
verify that the mail itself and Kerio were OK by fetching it with an older
version of Mozilla.

Reproducible: Always

Steps to Reproduce:
1. Receive a mail with more than 70 JPG attachments, each of about 100K in size
2. Verify that the mail is present on your IMAP server by looking in inbox
3. Click on the message to view it.  

Actual Results:  
Apparently endless looping.  Not a crash, but network access continued and CPU
activity was heavy.  It was possible to stop this by attempting to load another
message from the inbox.

Expected Results:  
Just load the mail and provide normal access to it and to its attachments.

I can confirm that it does the same here with Thunderbird 1.0.7 (20051217) (Gentoo Linux kernel 2.6.14).

What thunderbird is doing it's that when it wants to display an attachment (show attachments inline) it's downloading the full message. So for the 70 jpgs user the "endless" loop it's just that thunderbird is downloading the mail 70 times.

In my case the IMAP server was UW IMAP4rev1 v12.264.

please try a 1.5 build - this was fixed on the trunk a long time ago.
