User-Agent:       
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.6) Gecko/20040113

If I import a complete Mail Folder from Eudora Folder containing many
subfolders, Mozilla mail crashes. Importing succeeds with a smaller Eudora Mail
Folder (for example a folder with four mailboxes and 400 messages). 

Reproducible: Always
Steps to Reproduce:
1.Tools Menu
2.Import ...
3.choosing Mail, then Eudora format, then the folder

Actual Results:  
1. mozilla crashes 
2. after restarting mozilla and mail, only very few mail folders were actually
imported

Expected Results:  
Import the whole Eudora Folder

I just imported over 33,000 emails distributed across 41 subfolders from Eudora.
  No crash.

Reporter, can you narrow this problem down to a specific email?

Could you formulate again your question in other words ?
 I don't understand exactly what you means.

Well, you have a large mail folder in Eudora, and if you import it, Mozilla 
crashes after having gone part of the way. You also have a smaller mail folder 
that imports ok, which seems to suggest that it's the size of the folder.

However, comment 2 seems to indicate that maybe size isn't the problem, so I 
wondered whether it was a specific message (or messages) in those folders that 
was causing Mozilla to crash - we've had similar problems in the Outlook 
Express import, so it's possible.

So could you try importing the folders one at a time to work out whether you've 
got one or more 'bad' messages, then try to work out what message is causing 
the problem? Unforunately, because we don't let you choose what you're going to 
import (as far as I remember), you'll have to use Eudora to copy your mailbox 
bit-by-bit into another mailbox, then import that -- or back up your whole 
mailbox and repeated restore-and-delete-bits.

The alternatives are that either: a. you compile Mozilla and debug the problem 
yourself (a stack trace of the crash would help, if you can produce that), or 
b. you attach your mail folder to this bug.

OK. The strategy you are proposing is clear. 
So I will try to refine my tests.

Mail folders that are causing Mozilla to crash are typically some containing
html format messages. When restarting Mozilla mail, I see that the last
(incomplete) imported message is a html message. Meanwhile if I import only the
mailbox where the crash occurs, the mailbox is imported successfully.
So the size of imported folders is not the main cause as suggested in comment 2.
If that can help I am attaching an extraction of the mailbox where the crash
occurs (message with Subject:      SARC August 2001 Newsletter).

Sorry, are you saying that you *do* crash at this message when you import this 
mailbox, or that you only crash when importing more than one mailbox at the 
same time, but that it's always at this message in this mailbox, or something 
else?

I assumed what you've attached is the .mbx file for the mailbox. Is there a 
corresponding .toc file?

The mailbox I attached *doesnot* cause a crash by itself. The crash behave more
randomly than I thought after my first trials. I am importing a hierarchy of
folders whose total size is 340 Meg. The crash occurs at different steps (after
about 60 Meg imported or after 150 Meg in another test).It seems difficult to
send you a 300 Meg folder. The only way  would be a transfer by sftp from a
local server here.
I have no time to start a debugging by myself.

No, since Eudora 5 (Macintosh version) there are no more .toc files (difference
with the Windows version). Mailboxes are plain unix-like files.
