[Qt-creator] Autocomplete oddities

I went back and tested this issue against all of the versions of Qt Creator I
have installed here and came up with these results:
3.2.2 doesn't work
3.4.1 works correctly
3.4.2 works correctly
3.6.1 works correctly
4.0.0 doesn't work
4.0.1 (18-May-2016 snapshot) doesn't work

Not sure how helpful that is, but at least it's more data. I'd be happy to 
create a bug report if it's an issue others are seeing?
