User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Build Identifier: http://ftp.mozilla.org/pub/mozilla.org/thunderbird/releases/0.9/Thunderbird%20Setup%200.9.exe If I start writing an email, and save it into the drafts, it will be saved with format=flowed in content-type. When I open that draft for editing again, message compose window will not reassemble paragraphs correctly, they will be as if I typed new line at end of each line. On an example, say I was editing email, and saved it. Saved mail source will look something like this (I replaced last space in line with _): asdf asdf asdf asdf_ qwer qwer qwer qwer_ zxcv zxcv zxcv zxcv_ After reopening this draft for editing, and adding some text to second line and saving it again, content-type will still claim the format is flowed, but the source will look like this: asdf asdf asdf asdf qwer qwer uiop uiop_ qwer qwer zxcv zxcv zxcv zxcv You can see something is wrong even when editing, since compose window treats each line as it was separate paragraph (instead of treating all lines as one paragraph). When you view this new copy of draft, it looks rather odd: asdf asdf asdf asdf qwer qwer uiop uiop qwer qwer zxcv zxcv zxcv zxcv (which, of course, is correct representation of the source) Reproducible: Always Steps to Reproduce: 1. start writing mail, make couple of paragraphs long enough not to fit onto single line 2. save as draft 3. reopen draft for editing, and try adding text to existing paragraphs, try adding one new paragraph 4. save as draft (or send) 5. view this new draft (or sent mail) - formatting will be broken
