gnvim: set title in init.vim / vimrc crashes

How to reproduce: add set title to your startup routine, open with gnvim some_file.txt (it does not crash if you run just ‘gnvim’)

Workaround: Don’t set the title before the gui is there, use autocmd GUIEnter * set title (edit: actually, that simply never get’s executed 😉 )
