Status: RESOLVED INVALID

(Thunderbird :: Message Compose Window, defect)

[Daniel]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13

While sending/response a mail which includes more text than fits on a line (depending on current windows-width) so auto-line-break occurs, and you add a openpgps sign to the mail it becomes an invalid signature after saving/sending it.

I think the problem is that this autolinewraps are saved after the mail goes 
through openpgps encryption. 
Why you are saving the autolinewraps in first place? -they depend on the screen resolution and window width so you don't need to save them and they doesn't matter

Reproducible: Always

Steps to Reproduce:
1. click on write
2. insert text with spaces, longer than current window-width until the line automatically wraps into next line
3. click on OpenPGP->Sign Mail
4. send the mail or click on send later
5. open the mail from the Sent, Unsent or Inbox folder and you see a broken signature

steps to repair it manually:
1. save the mail with invalid signature into a file
2. open the file with an editor
3. remove the unwanted autolinewraps so the mail looks like the original and save it
4. click on Open Saved Message... and open the file in tb
5. now if you edited it right the signature should be valid again
Actual Results:  
OpenPGP Security Info
Error - signature verification failed
gpg: BAD signature from ...

Expected Results:  
OpenPGP Security Info
Good signature from ...

That's an Enigmail bug, nothing to do with Thunderbird.
