git-quiltimport complaining yet still working

In git 1.5.1 the quiltimport function started complaining in a new way:

	libata-clear-tf-before-doing-request-sense.patch
	Patch is empty.  Was is split wrong?
	/usr/bin/git-quiltimport: line 78: stop_here: command not found

yet it still applies the patch properly.

For an example of patches that causes this output, the -stable kernel tree queue can be used (which is where I started seeing this problem...)

Any hints?  Or is it time to start bisecting?

thanks,
