Developer tools do not open as a function: they open because there is an error somewhere! Unfortunately, Chromium (on top of which Atom is built) does not show the full stack unless dev tools are open before an exception occurs.
First, try opening them using View β Developer β Toggle Developer Tools (or run the Window: Toggle Dev Tools command from the palette) and try to reproduce the problem by double-clicking on the word. You should now see the full stack, hopefully including an indication of the package causing the problem.
