Another (similar?) problem with non-ascii-chars:

	$ git send-email --to 'Will Deacon <will@kernel.org>' --to 'Krzysztof Wilczyński <kw@linux.com>' --to 'Lorenzo Pieralisi <lpieralisi@kernel.org>' --cc 'Rob Herring <robh@kernel.org>' --to 'Bjorn Helgaas <bhelgaas@google.com>' --cc 'linux-pci@vger.kernel.org' --cc kernel@pengutronix.de -1 --base=@~
	Use of uninitialized value $address in sprintf at /home/uwe/gsrc/git/git-send-email line 1162.
	error: unable to extract a valid address from:

Bisection points to the same commit, when dropping ń in Krzysztof's
name, it works fine.

Best regards
