1. Open a file.
2. Drag the 'Problems' view into the editor stack.
3. Close the 'Problems' view.
4. Drag the file's tab and "split" the editor stack. It will not actually split of course.
5. Close the editor.
6. The editor area is now gone. Reopening an editor will bring it back.

It comes back now but I get an NPE. If I open the 'Problems' view first there doesn't seem to be a problem.
