Thanks to the incredible work done by Martin Pitt and to Adam Conrad (who did the buildd changes required), Ubuntu edgy is now getting debug symbols for all the packages. You can read the announce for details on the topic.
Easy steps to try it:
The tools are running since yesterday only so not a lot of packages are available from it right now but it's only a matter to rebuild packages, the GNOME stack should be mostly rebuilt with GNOME 2.16.1 by example
Happy bug triage to everybody and don't forget to hug Martin and Adam for their work ;)
