NullPointerException after Idea launched

[Kwaq]

Sometimes I'm getting NPE after lauching IDEA (15.0.2) or opening project.

Below is the stacktrace.

Thank you for reporting the issue. I will try to reproduce it. Does it happen every time you try to go to a related file? What configuration did you use in the settings page?

As for the first question: probably not, because it happens sometimes and only after Idea startup. I did not relate it to particular file. And here are my settings.
