export BYOBU_DISTRO=Ubuntu
[ -r /usr/share/byobu/profiles/bashrc ] && . /usr/share/byobu/profiles/bashrc #byobu-prompt#

Then the problem goes ways. The issues appears to be in /usr/share/byobu/profiles/bashrc, specifically:

The "Googley Colours" terminal sequences obviously have some kind of issue solved by the more complicated Ubuntu definitions.
