Status: RESOLVED WORKSFORME

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: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

This bug has occured since at least 1.0, and is still present in the beta.
Whenever I try to import my mail from Outlook Express, there is one folder that,
when viewed, causes Thunderbird to hang.  This is a large folder/mailbox
(150MB), but I have larger folders that work fine. Thunderbird states that is
building a summary file, and a summary file of the correct apparent size is
created, but it hangs afterwards. After restarting the program, an attempt to go
to that folder hangs it again.
Importing from Outlook gives the same error. Mozilla M&N has absolutely no
problem importing the folder from Outlook Express, though. I can view the folder
fine in Mozilla, but when I then try to import the folder from Mozilla into
Thunderbird, Thunderbird hangs when I try to view the folder.
The problematic folder is at the listed URL (it's 30 MB, zipped). Unzip it into
your Thunderbird profile and try to load it, and it hangs. Unzip it into a
Mozilla M&N profile, and it works.

Reproducible: Always

Steps to Reproduce:
1. Import mail from Mozilla Mail & News, Outlook, or Outlook Express -or-
1a. Download the file from the given URL (30MB) and unzip it into your
Thunderbird mail directory.
2. Go to the problematic folder
3. If the mail was imported from Mozilla, it immediately hangs. If it was
imported  from Outlook, it hangs after building a summary file.

Actual Results:  
Thunderbird hangs (for at least 12 hours), and has to be shut down.

Expected Results:  
It should load the mail, and let me view it

I've uploaded a much smaller example:

(zipped), and it shows the same problem.

Well, I've just installed the newest version of Thunderbird and imported everything, and there was no hang. I guess it's fixed.
