There is a crash that occurs at least with Cucumber tests in a code like

Then("{string}") do |string|

expect(foo).to include string

end

that is caused by kdev-ruby to recognize include function as a mixin insert rather than a method.

This commit makes the crash disappear, but I don’t know kdev-ruby (nor kdevplatform’s API) well, so there may be some better solution to this problem. Please say if there is something I should do differently.
