@igi: I don't know if it is the the same bug, but I have both thunderbird and thunderbird-globalmenu 3.1.10+build1+nobinonly-0ubuntu0.11.04.1 installed and I can select Thunderbird in Preferred Applications but Natty won't honour my selection. If I exit and restart Preferred Applications, Thunderbird stays selected, but mailing from Libre Office, Draftsight or Firefox starts Evolution.
