[yocto] [Hob] failed to add "packagegroup-core-full-cmdline" properly

[Steve Rae]

- using jethro
Running Hob:
- machine = raspberrypi2
- image = core-image-sato
- edit image recipe - include: packagegroup-core-full-cmdline
Build packages: is successful (1997 packages)
Build image: fails (right at the start) with:
       Nothing RPROVIDES 'liborc-test-0.4' (but 
/home/srae/work/poky/hob/recipes/images/core-image-sato-edited-20160121-140708.bb 
RDEPENDS on or otherwise requires it)

Any ideas?
Thanks in advance, Steve
