By daniel-kullmann:

Well, my problem is as follows: I edit some files using nerdtree. Then I remove all the files from vim, while keeping the window open. Then I switch to nerdtree again and start opening new files. And there I get a new split window, because nerdtree treats a window with &buftype=nofile as a window that should not be tocuhed.
