I tried to fump the whole history of qemu with format-patch.
It crashes both with v2.0.0-rc2-21-g6087111
and with git 1.8.3.1:
~/opt/libexec/git-core/git-format-patch --follow -o patches/all
e63c3dc74bfb90e4522d075d0d5a7600c5145745..
Backtrace:

Did not debug further: could be related to the fact
swap is disabled on my box, so attempts to allocate
huge amounts of RAM might fail.
Still should not segv I think ...
