Please, devs. This is a big deal. I've lost work due to this bug.
An amendment to djerius' workaround: you can keep the close-on-exit functionality without killing the current window if you include `-a` along with `-k`. So...
grep new-window /usr/share/byobu/keybindings/f-keys.tmux \ | grep ' -k' \ | sed -e 's/ -ak//' \ >> ~/.byobu/keybindings.tmux
