Do what lijenstra said.

bugger.blend

optionally open bugger.blend, maximize both windows (one of them should have no content) press F12, get a crash in render_open_view

BKE_screen_find_big_area returns null, gets dereffed , which naturally crashes..

I can not reproduce the issue on Linux. It's also weird why you mention one window has an empty content. This doesn't sound right and might very well be a reason of actual crash.

So afraid it is up to you to investigate why window have no content ;) Maybe @brecht will have some clues here as well? :)
