As the import only had access to the SF user names for bug reporters, commenters and assignees, it was not possible to link them up to existing Launchpad users in most cases. This means that duplicate person objects have been created with email addresses like $USERNAME@users.sourceforge.net.

If you are a Launchpad user and have previously filed or commented on Inkscape bugs, you can clean up the duplicate person object by going to the following URL and entering your $USERNAME@users.sourceforge.net address:

https://launchpad.net/people/+requestmerge

After following the instructions in the email confirmation, all references to the duplicate person will be fixed up to point at your primary account (so bug mail will go to your preferred email address rather than being redirected through SourceForge).
