Steps to reproduce:

 1. Disable smart HTTP[2].
 2.
	git init reproduce
	cd reproduce
	git remote add clam http://git.clamav.net/clamav-devel.git
 3. git fetch clam
    Wait a few seconds (there will be no output).  Hit ^C.

$ ls .git/objects/pack/ pack-98c82c9d2da21d2efddc4544d68332235795df19.idx.temp.temp $ git fetch clam error: wrong index v2 file size in .git/objects/pack/pack-98c82c9d2da21d2efddc4544d68332235795df19.idx.temp error: Unable to find fe96c524670f23f73008c0e6b4001c096e4f9532 under http://git.clamav.net/clamav-devel.git Cannot obtain needed object fe96c524670f23f73008c0e6b4001c096e4f9532 error: Fetch failed.

Ideas? Jonathan
