X-Launchpad-Bug

The X-Launchpad-Bug header collates most of the other information about a bug’s status, importance, etc. It gives you slightly different information, depending on whether you’re dealing with a distribution package or a project:

Project

  • product

  • status

  • importance

  • assignee

  • For example: X-Launchpad-Bug: product=terminator; status=Confirmed; importance=Low; assignee=None;

Package

  • distribution

  • sourcepackage`

  • component

  • status

  • importance

  • assignee

  • For example: X-Launchpad-Bug: distribution=ubuntu; sourcepackage=exaile; component=universe; status=Confirmed; importance=Medium; assignee=None;

Bug mail rationale

The X-Launchpad-Message-Rationale header tells you why you’ve received the notification.

You can be either:

  • Assignee

  • Subscriber

  • Registrant

For example: X-Launchpad-Message-Rationale: Assignee

An @ symbol shows that you’re related to the bug through membership of a team:

X-Launchpad-Message-Rationale: Assignee @ubuntu-kernel-bugs
X-Launchpad-Message-Rationale: Subscriber @ubuntu-core-dev

If you’re the project/package owner, the product/package name is show in parentheses:

X-Launchpad-Message-Rationale: Registrant (kiwi)

If the notification is about a duplicate bug, the rationale shows you which bug this report duplicates:

X-Launchpad-Message-Rationale: Assignee via Bug 1332

This makes it easy to filter out bug mail about duplicate bugs. For example: let’s say this bug notification is for bug 2129. This header means you are the assignee of bug 1332, of which 2129 is a duplicate.
