These are too many packages for me to file individual bug reports for each of them, so I am filing an overall bug to track this.

[d-d-2 (dandromb)]

I can link this as "also affects" to all the various packages, if that is helpful.

[Matthias Klose (doko)]

thanks for doing that, however the work doesn't go away. do you have tested patches to address these?

[d-d-2 (dandromb)]

I have no tested patches, as I don't use these packages. Just trying to catalog the TODOs.

I am also, perhaps more-importantly, unfamiliar with the workflow to create patches for this, but I could get involved with trying to fix them if I knew how.

- What source tracker is it (git, bazaar, etc) and where are the repo links for these packages?
- Would I be able to upload my patch in my own forked code repo or just post patches as text?
  - Where to post patches to get them seen or reviewed?
- Any docs/cheat sheets to get up to speed with this workflow?
