1. The evince AppArmor profile is enabled in the default install of Ubuntu. Thunderbird users clicking on a mailto: link in a PDF are presented with an error message stating that thunderbird can not be opened. Under some circumstances, this seems to work ok, but setting the mailto: application System/Preferences/Preferred Applications via will trigger the bug. Also, I'm told by the mozilla team that the thunderbird3 path needs to be added for the pending 3.0 - 3.1 migration.

2. The following is now being used in /etc/apparmor.d/abstractions/ubuntu-email in the development release of apparmor (2.5.1~rc1-0ubuntu2):
  /usr/lib/thunderbird-3*/thunderbird{,.sh} PUx,

This line is what should be added to Lucid.

3. attached is the proposed patch

a) install thunderbid with 'sudo apt-get install thunderbird'
b) go to System/Preferences/Preferred Applications and select Thunderbird as the mail reader
c) open the attached test_hyperlink.pdf (from lp:qa-regression-testing) and click on the email hyperlink

5. The regression potential is considered minimal since only more access is being allowed in the ubuntu-email abstraction.
