This regressed somewhere in here: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=a884b96685aa13b65601feddb24e5f85ba861561&tochange=f3f2fa1d7eed5a8262f6401ef18ff8117a3ce43e

My bet is bug 1208217, :mystor what do you think?
Flags: needinfo?(michael)
Keywords: regression
Firstly, I've looked at the changes for bug 1208217 again, and I'm not sure how it could have caused this increase in warning spam. I'm also not convinced that this warning is super legitimate as an actual failure case (it was changed from a if (!editor) return NS_OK; by a regular expression in bug 572618), and the warning itself should probably be removed. 

I'm going to check with ehsan to make sure that my assumptions are correct.

We should remove this warning.  r+ on a patch that does that.  :-)

Disable warning in nsDeleteCommand::IsCommandEnabled, r=ehsan
Alright I got my bisector working again, for posterity it looks like it was actually this push that regressed: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=83e8b01535bf1b574338859b8e26e2f1a86030e0&tochange=ea96f5a5d0b523b19627b1b98e25a28e956890dc

Appears to be updating tests.
