Thunderbird 1.5.0.5 is released, the download page does not list it while I write this but you can find it through Help > Check for updates, unless it downloads it automatically.

Thanks Thomas!

Spooky, I hadn't even finished reading this page and firefox told me it was ready to install

Edit - actually both firefox and thunderbird updated themselves at the same time, sorry I got confused!

Got it already, thanks Thomas!
