I could add to this that what "solves" the problem is to refactor the project name to a new one; eg, if your project is called test, then refactor it to test2 and the problem is solved. When going back to the old name ("test" in the mentioned example), the problem will still be gone. This is not a nice solution however (especially if you have your project in git/svn etc) ... and the fact that it works makes the whole problem even more weird.
