Comment 12 for bug 1279533

well, this is quite a catch, when you start byobu with already existing sessions, it basically expects that you choose what session you would like to restore. However gnome shell does not offer any "window" where it will print such question and process will just hang (you can try to do it with "yes" command, when you run it from gnome shell (alt+f2), it keeps running and eating system resources and you do not see it's output anywhere. This is reason why this crashes, it is looking of encoding of stdout, however there is no stdout, so there is no encoding of stdout, I can fix that it will not crash, however that is not really solution, just workaround to stop crashing without fixing issue that you would not be able to start byobu this way.
