Comment 6 for bug 630281

Thank you for bringing this bug to our attention. However, a paper cut should be a small usability issue, in the default Ubuntu install, that affects many people and is quick and easy to fix. So this bug can't be addressed as part of this project.

 - We dont include Thunderbird in the default install. Hence not a papercut
For further information about papercuts criteria, please read https://wiki.ubuntu.com/PaperCut.
Don't worry though, this bug has been marked as "Invalid" only in the papercuts project.
