indeed the crash very often happens when I move the frame (Emacs fails
to place and size itself properly on startup, so this is the first thing
I have to do. I keep Emacs maximized - but _not_ full screen).
Another thing is that Tramp appears to be broken recently - it keeps
timing out even though I can ssh to the remove host without any problems.
