Trying to call `git cl upload` gives the following error:

I was able to bypass hooks and the patch seems to be on its way to land (chromium_presubmit is green).

I tried to revert a recent CL but it led to other errors. I would prefer to leave this to people who actually know what they are doing or have time to look into it :)
