That was my first try, it didn't help.
I'm also not sure if do_package() is executed under pseudo by default.
Also since the command is a pipeline, I don't know if pseudo is
propagated from one command to the next.
Actually I feel a bit as a sorcerer apprentice when it comes to
python/pseudo/packaging.

I added some text to bugzilla. The gist is: In poky the sources are
not deployed.
No source files, no wrong ownership.

What I did is doing a repo setup of angstrom master.

Removed the following from bblayers.conf because of parsing errors:
  ${TOPDIR}/sources/meta-uav
  ${TOPDIR}/sources/meta-kde4
  ${TOPDIR}/sources/meta-edison
  ${TOPDIR}/sources/meta-atmel
  ${TOPDIR}/sources/meta-minnow
  ${TOPDIR}/sources/meta-altera

And then:
. setup-environment qemux86
bitbake core-image-minimal
