I'm using separate Chromium and WebKit git trees, and run-perf-tests bombs when attempting to collect revision info:

Traceback (most recent call last):
  File "Tools/Scripts/run-perf-tests", line 40, in <module>
    sys.exit(PerfTestsRunner().run())

    raise error

It boils down to git not supporting querying resources outside its current tree:

fmalita at fmalita-linux2:~/wk$ git log /mnt/screamin/src/chromium/src/build
fatal: '/mnt/screamin/src/chromium/src/build' is outside repository
