515731 - Opening Drafts folder on IMAP results in an alert regarding a failure

Status: NEW

(Thunderbird :: Folder and Message Lists, defect)

Description

[Ryan Foster]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.4pre) Gecko/20090910 Shredder/3.0b4pre

Every time I attempt to open my Drafts folder on my IMAP account, Thunderbird presents an Alert Dialog containing the following message:

> The current command did not succeed.  The mail server responded:Can't save a > zero byte message.
>
> .

The tab for the folder then continues to display the "working" throbber instead of the icon, which implies that Thunderbird may be stuck in a loop.  Selecting a different folder will function normally, but selecting the Drafts folder again will result in the same behavior described above.

Reproducible: Always

Steps to Reproduce:
1. Open the 9/10/2009 nightly of Thunderbird
2. Connect to an IMAP account
3. Select the Drafts folder
4. Receive alert
Actual Results:  
Thunderbird produced an alert:

> The current command did not succeed.  The mail server responded:Can't save a > zero byte message.
>
> .

Expected Results:  
Thunderbird should not be producing such an alert unless I actually had a zero byte message open that I was attempting to save.

An imap protocol log would be interesting - https://wiki.mozilla.org/MailNews:Logging

Opening a drafts folder shouldn't cause us to save a message - I'm not even sure what "save a > zero byte message" means in the imap protocol context.

Oh, apparently my copy/paste and attempt to quote the alert message got eaten.  The alert was:

The current command did not succeed.  The mail server responded:Can't save a zero byte message.

Attachment: IMAP log

IMAP log as requested.  I scrubbed out my tags, but left the rest of the log intact.  It should cover the IMAP actions for all default folders, and some "idle" activity.

ah, you have an offline playback event in your drafts folder, and it seems to be corrupted - perhaps you could e-mail me privately your Drafts.msf file and I could have a look. After that, you can do a right click, bring up properties on your drafts folder, and click rebuild index. Then you should be able to open the drafts folder w/o getting an error from the server.

The drafts.msf file is in your user profile directory, either under local folders if it's a local drafts folder, or under the imap server directory, if it's an online drafts folder.

David,

I've sent you the file as requested.  I then rebuilt the index and the error no longer occurs at this time.  Let me know if you require any follow-up on my part.

we should have noticed that the offline operation would cause an attempt to append an empty message to the imap server, and removed the offline operation.
