208246 - Malformed mail message causes hang of mozilla (and several other problems)

Status: RESOLVED WORKSFORME

(MailNews Core :: Backend, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3.1) Gecko/20030425

I occasionally have problems with moving large amount of emails from my
inbox(imap) to my local folders. At one point I could reproduce it so I did some
more investigation. It also tried moving FROM an imap-folder TO an imap-folder
and it didn't have this problem. After a day of testing it discovered that the
problem is/was caused by a single (spam)-message which was unreadable by Mozilla
mail. When I tried to read the message mozilla simply hangs or it shows the
animated busy-indicator ("busy-bar"). I think a lot of mail problems can be
tracked back to this issue. 

Because a move between 2 imap folders is performed at the low (server-)level
(which doesn't require mozilla to actually read the message itself), a corrupted
message doesn't pose a problem. But reading, moving, copying the message to a
local folder requires mozilla mail to read the message, which hangs mozilla

Reproducible: Always

Steps to Reproduce:
1. Try to "read" the corrupted message
2. 
3.

Actual Results:  
Mozilla hangs and sometimes it shows the busy-indicator (which keeps "running").

Expected Results:  
Mozilla should detect the message is corrupted or Mozilla should timeout after a
reasonable amount of time.

A have a sample file (folder) with a corrupted message in it.

sorry for the spam.  making bugzilla reflect reality as I'm not working on these bugs.  filter on FOOBARCHEESE to remove these in bulk.

message reads fine from local folder with TB version 2.0.0.7pre (20070922), though it's already garbage.
