I found a bug, how do i report it?

Information on reporting bugs including what to do and what not to do.

Bugs are bound to happen every now and again (especially when using the unstable tree) - we want you to report them so we can get them fixed!

Bugs can fall into any number of categories - there are a couple of ways you can report them.
Good ways to report a bug:

Use the issue tracker
Use the mailing list, subscribe/archive information is located on the community page. (especially report upstream bugs - such as ones found in tuxonice, reiser4, aufs, etc.) - partially because developers of these projects maybe subscribed.
Report it on IRC (acceptable for minor bugs, such as typos, simple compile errors, etc)

Bad ways and bad things to do when reporting a bug:

Sending an email (If you don't use the mailing list or bug tracker - which both send us email notifications)
Reporting the problem with Zen somewhere other than us, examples: Reporting a Zen problem to another project such as Gentoo, reporting a kernel problem with Zen to an upstream kernel developer (Unless you are absolutely SURE it is an upstream problem, if you report it to us first we can possibly fix it ourselves and submit the fix upstream - or direct you where to report it)
Posting a bug without a trace or information, EX: "Zen doesn't compile" instead of "soandso.c doesn't compile in version 2.6.x-zeny, below is an attached .config and the exact error as i saw it"
Yelling about it, EX: Say that you were having a problem with drm in 2.6.31 (not zen, just 2.6.31) - and we directed you to upstream to report the problem and you respond "F@*& YOU, You SUCK, FIX IT" (this has actually happened - an upstream bug that someone expected us to report/fix - when none of us were affected by it)
