Bug Reporting (3) A Bug's Life Cycle

We're at the end of post-beta 1 bug triaging week. When we triage, we first ensure the product (KDE program) and component (product sub area) are right for the bug report and that the title is accurate and in English.
A bug report goes through various stages until it is closed. First stage is UNCONFIRMED status. Bug squad people mainly try to reproduce your bug. When this is done, the report can move to the NEW status, a comment is added about the version on which it is reproduced on and the maintainer then knows that this is serious. The bug can also move from UNCONFIRMED to CLOSED as a duplicate. The bug number is added to the duplicate report in order to tell it that there was another person reporting it.
Sometimes the triager or the maintainer would like more information about the bug: the backtrace is not accurate enough because some debug packages are missing, the procedure to reproduce is not clear enough, a screenshot would show the problem better,... A comment is added to ask for more information and the bug is marked as WAITINGFORINFO. The reporter in most cases then adds the information so it's easier to understand the problem and the bug moves back to UNCONFIRMED or NEW.
Developers look at the problem and fix it if they reproduce it or if they find the cause. When it is fixed with a code change, the svn revision is included in the bug report which is then closed. Death of the bug!

Sometimes the bug is from third part components which were not updated correctly to the new libs version (some plasma applets for example that you get from kde-look.org) and the bug is closed as RESOLVED as DOWNSTREAM. You are then invited to report it to the author.
