[yocto] New issue with git fetcher?

[Scott Garman]

Hi Richard,

This afternoon I performed a build from scratch using master, which 
included your git fetcher change to use mirror tarballs 
(1077021f7010388e889d85630b13c4c7901d7718).

When I performed my build from scratch (using a pre-populated DL_DIR 
from previous builds), linux-wrs failed on do_fetch, with the following 
in log.do_fetch:

 From git://git.pokylinux.org/linux-2.6-windriver
   * branch            common_pc-standard -> FETCH_HEAD
  From git://git.pokylinux.org/linux-2.6-windriver
   * [new tag]         v2.6.36-rc5 -> v2.6.36-rc5
   * [new tag]         v2.6.36-rc6 -> v2.6.36-rc6
  NOTE: Creating tarball of git repository
ERROR: Task failed: Unknown fetch Error: coercing to Unicode: need 
string or buffer, NoneType found

I performed a -c clean and then -c fetch, but ran into the same problem.

I then went and deleted the linux-wrs-related sources from DL_DIR, and 
ran -c clean and -c fetch again, and it looks to me like the fetcher is 
actually downloading tarballs from the source mirrors first, and then 
trying git directly:

NOTE: Running task 130 of 130 (ID: 0, 
/raid0/sources/poky/meta/recipes-kernel/linux/linux-wrs_git.bb, do_fetch)
NOTE: package 
linux-wrs-2.6.34+git0+b67e060194a38c6331da1532bd06446087a42b3b_0+0431115c9d720fee5bb105f6a7411efb4f851d26-r12:

NOTE: fetch 
http://autobuilder.pokylinux.org/sources/git_git.pokylinux.org.linux-2.6-windriver.git.tar.gz

I confirmed this by seeing wget running in my process list, and then git 
eventually shows up.

Finally, I get the bitbake message:

NOTE: Creating tarball of git repository

...and I see gzip running, but the task ends up failing with the same 
error as the log.do_fetch example I mentioned above.
