Comment 31 for bug 525552

The bug was about byobu not reading PS1's formatting in ~/.bash_profile. The fix apparently goes along "so just do not specify it there", which I would not go as far to call it a fix.

My fix, if you can also call it that, is, instead, going to Menu > Create new windows > Command: /bin/bash --login, and tick "add to default windows" (the only one I have). Cannot tell for other shells since I just know bash.
