We switched to using Gtk.SourceCompletionWords recently rather than our own provider but this has not been released yet. I'll test the latest source with the file you mention.

[jeremypw]

I did not have any problem browsing or performing word completions on the file you provided using the current master branch so I guess the problem was in the old discarded provider.

[jeremypw]

I'll close for now - please re-open if you find a problem with the master branch
