Uncaught TypeError: Cannot read property 'getTokenIterator' of undefined

[jackocnr]

1. Open a file with this contents: https://gist.github.com/jackocnr/dcd20c4aca0d07849f3c
2. Save it

Note: I've removed as many lines as I can from that file to still repro the error. If I remove any of the existing lines (inc a blank line e.g. line 27) I don't get the error any more...

Atom Version: 1.5.4 System: Mac OS X 10.11.3 Thrown From: auto-detect-indentation package, v0.5.0

Same issue with this: https://gist.github.com/weotch/cb231c20179a7a65ef22

I'm unable to reproduce with either of these files. does it happen on every load/save of the file?

[jackocnr]

Yes I was getting the error every time I saved (I got very used to dismissing the error popup every time I saved). But now I don't get it any more... Perhaps it was a clash with another plugin at a specific version? I've had lots of updates recently.
