User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729)

If mail.strictly_mime is true, and using non-English characters, mail body is encoded in quoted-printable. After decoding, spaces between some words are lost. Reproducible on editing draft message, forward, edit as new etc.

Reproducible: Always

Steps to Reproduce:
1. Create new message with body: "раз два три четыре пять шесть семь восемь девять десять" (possible any non-English characters, without quotes).
2. Save as draft.
3. Edit. You'll see: 
Actual Results:  
"раз два три четыре пять шестьсемь восемь девять десять" - space between 6th and 7th words is lost.

Expected Results:  
"раз два три четыре пять шесть семь восемь девять десять"

I can confirm this issue with this STRs:

1. set mail.strictly_mime = true
2. select an HTML account;
3. create a new message with this body раз два три четыре пять шесть семь восемь девять десять
4. save message as draft
5. edit draft then observe behavior descrived in comment #0

It's an editor problem?

Doesn't look like it, but can't tell for sure without debugging.
