Hi Jens,
It seems there where 2 (not one) places where I had the same race
condition. I managed to reproduce the bug by clicking ctrl-up like mad,
so I put in a traffic light and now operation should be normal. It could
also be solved with a queue, but I'm not sure if it's worth the extra
code to do that.
