I have found a note that this may be the result of an interrupted git fetch (ctl-C or network timeout):

	<http://stackoverflow.com/questions/10671638/how-to-fix-git-repository-broken-by-interrupted-git-fetch>

And it may be a more common problem:

	<https://groups.google.com/forum/#!topic/mozilla.dev.b2g/RViAG2cNYws>

Then I tried on my local copy:

	cd .repo/projects/kernel/goldelico/gta04-kernel.git
	git fetch goldelico

and also got this message - with a different object hash.

Running git gc didn't change anything.

But git fsck did report some "dangling commit" including the
one reported as "while processing commit" by git fetch.

After some more google I found this command sequence:

	git fsck
	git reflog expire --expire-unreachable=now --all
	git gc --prune=now
	git fsck

I still had some (which are empty so I removed them)

	bad sha1 file: ./objects/38/798e0f084bf9dcf31a9c6de871e53dabc2ae3d.temp

Then, a git fsck did run completely clean.

But git fetch still failed.

So this is not the real problem.

Another bug report confirms that it is a git ctl-C bug (and neither server nor client nor repo):

	https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=602528

The solution appears to be (ignore the "does not point to a valid object!" errors):

	cd .repo/projects/kernel/goldelico/gta04.git
	rm objects/pack/pack-*.idx objects/*/*.temp
	git fetch goldelico

The fetch will then run several ten minutes (so be patient and don't ctl-C).

Hope this helps for you as well.

BR,
Nikolaus
