[oe] Extending bug20 support in stable

[Stefan Schmidt]

Hello.

Thats a first small set of patches to sync back bug20 and later bug framework
support ino stable. Its an ongoing process but I wanted to get them in piece by
piece instead of throwing them in after a release was done.

One small gettext depends fix is included as well.

Please give it some good testing and let me know if something breaks.

regards
Stefan Schmidt
