Changing messages in outgoing folder may send the message twice

[Martin Bergner]

When editing an email in the outgoing folder, evolution will send the email twice.

Steps to reproduce:
0. Prerequisite: No saved passwords
1. Write email, try to send it -> evolution asks for the smtp password
2. press cancel -> the message is in the outgoing folder
3. Open the message, change something
4. click send again

Result: you now have two messages in the outgoing folder
Expected: Change the message, send only the changed one

Why is this bug relevant (use cases):
1. When prompted for the password, you remember that you forgot something and decide to change it.
2. When prompted for the password, you realize that you chose the wrong FROM address (for multiple accounts) and decide to change it

Evolution version 2.32.2-0ubuntu7, Ubuntu Natty

If I remember correctly, this problem was also present in earlier versions.

I confirm the bug exists and would advise:
1- save messages as drafts on the first place when possible
2- save your password on evolution and lock your user account if you don't want other people to use it
3- don't use evolution, there are better alternatives, 11.10 will have thunderbird integrated.
