Ok, this is almost certainly what's up. For some strange reason your git 
binary segfaults on the clone. The scary thing is, it left your cloned 
repo in a bad state without even telling you. That's not good.  Normally 
we should always die() and give a _reason_ for a failure.

If you have that particular git binary, doing a

	gdb git

and then at the gdb prompt doing

	x/5i 0x0000003f5eb709d0

will at least tell where the SIGSEGV happened, but it doesn't give a 
backtrace so unless it's obvious, it can be a bit hard to debug remotely..
