518304 - (IMAP) Wrong error/info dialog shown when auto saving draft during compose (to non-existent drafts folder)

Status: UNCONFIRMED

(Thunderbird :: Message Compose Window, defect)

Description

[Thomas]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 GTB5 (.NET CLR 3.5.30729)
Build Identifier: 2.0.0.23 (20090812)

The following dialog is erroneously shown when composing a new message and it cannot be saved to the drafts folder:

'Confirm'
?  'There was an error copying the message to the Sent folder. Retry?
OK   Cancel

The message should read 'Drafts' folder - having something related to 'send' appearing while you are typing is extremely confusing (panic: did I already click send by accident?!)

The drafts folder doesn't exist because this is a Google hosted account, and after a locale change in gmail the [Gmail] folder was renamed to [Google Mail], presumably to comply with European rulings about the gmail brand.
At this point Thunderbird has not yet updated the IMAP folder list, and in effect the designated Drafts folder for the account in question is not available.

Reproducible: Always

Steps to Reproduce:
Note: I didn't do it this way, but would expect the same thing to happen since it is just a UI bug:
1. You may need access to IMAP server folders (directly on server)
2. Create IMAP account and create/assign drafts folder
3. Open compose window and type something
4. Go to IMAP server and rename or delete the drafts folder directly on the server
5. Return to compose window
6. Wait for autosave timeout to expire
Actual Results:  
Dialogue shown:
'Confirm'
?  'There was an error copying the message to the Sent folder. Retry?
OK   Cancel

Expected Results:  
Dialogue shown:

'Confirm'
?  'There was an error copying the message to the *Drafts* folder. Retry?
OK   Cancel

It's really 'a big that should be fixed', but I am sure it has been around for some time, so nobody noticed = not urgent.
