  for a quick test, i started a new project on my fedora rawhide
system:

* latest checkout of poky
* core-image-minimal
* qemuarm (as opposed to initial qemux86, just to be different)

  the initial fetch worked fine (taking advantage of numerous tarballs
i've collected over the months):

  $ bitbake -c fetchall core-image-minimal

  then:

  $ bitbake linux-yocto

which quickly produces the error at the bottom of this note as
displayed by "bb". i'm baffled ... does the kernel tree have some
new, untracked garbage in it that is causing this?

  the native git is version 2.3.0.
