Bug Wrangling
Libav manages bugs through multiple communication channels, helps in tracking what is fixed or it is still pending is important. Most Libav developers focus on irc and mailing lists and bugs are quickly fixed if they are reported there quite often, nonetheless bugzilla is somehow better in tracking harder to reproduce and fix issues.
Sifting bugzilla to make sure the issues reported there are not overlooked is warmly welcomed.
Checklist
Make sure duplicated bugs are marked as such.
Ask the reporters if they can provide samples and backtraces if they are reporting bugs.
Ask the reporters that need improvements if they could discuss on irc if the request seems vague or needs further details.
Mark bugs that seem to be fixed as such.
Ask the reporters of old bugs if the new version works for them in case the bug is somehow elusive.
