After hitting on rip CD the GUI hangs with latest master.

        Move out of the loop when the iterator is deleted in the loop.

Not sure, but running `top`, ruby shows up high on the list. Running `sudo perf 
record -a` and then `sudo perf report` I see the following.

My guess is, that is some kind of race.

I forgot to say, the window is just grey and no status information were written 
to it for over ten minutes. So I assume it hung.
