avrdude.conf: programmer type must be written as "id_type"? I'm trying to compile &amp; run using ino.

At the ino upload step I get the following error:

avrdude: error at /usr/share/arduino/hardware/tools/avrdude.conf:332: programmer type must be written as "id_type"

Relevant section of avrdude.conf:


programmer
  id    = "wiring";
  desc  = "Wiring";
  type  = wiring;   # line 332
;


I've seen various posts around the internet that suggest I just delete the config &amp; refresh it, but I'd like to find the correct syntax and actually understand &amp; fix the issue.
After looking at the source repo it looks like quotes are now required:


  type  = "wiring";
