452552 - spurious automatic send attempts for non-English-character-containing mail

Status: RESOLVED DUPLICATE of bug 328938

(Thunderbird :: Message Compose Window, defect)

Description

[Ian Clark]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: 2.0.0.16 (20080708)

When composing mail with non-English characters (Japanese specifically - no other languages attempted), T-Bird pops-up warning dialog "The message you composed contains characters not found in the selected character encoding...and illegible by the recipient" with options "send in UTF-8", "send anyway", and "cancel". This is the message that does and should pop-up when the mail is sent, but it pops up spuriously every ~5 minutes, probably during an auto-save.

Reproducible: Always

Steps to Reproduce:
1.switch input to Japanese.
2.type anything.
3.wait a few minutes.
Actual Results:  
T-Bird pops-up warning dialog "The message you composed contains characters not found in the selected character encoding...and illegible by the recipient" with options "send in UTF-8", "send anyway", and "cancel".

Expected Results:  
nothing

I've had this happen on a windows XP box, and the two latest Mac OS X versions.
