Oh, okay, I see it now. Couldn't reproduce it before because my config 
contains this line:

  (setq ruby-deep-indent-paren (delete ?\( ruby-deep-indent-paren))

Which logically shouldn't have any effect because we're not doing any 
indentation, but unfortunately does.

So I'm going to go ahead and try to fix it by removing the offending 
code. From some moderate testing, this doesn't seem to have any actual 
effect on indentation (the non-SMIE variant), and fixes the error. Let's 
see whether we get any breakage reports later.

Commit 2725254ab5.
