Comment 5 for bug 1279533

Description of problem:
I just ran `sh -c byobu` in Xfce via "Run..." (Alt+F2).

BTW I have instaled byobu just few moments ago and at the moment when it crashed I was running one session. (I wanted to access that using above command.)

Version-Release number of selected component:
byobu-5.69-2.fc20

Additional info:
reporter: libreport-2.1.11
cmdline: python /usr/libexec/byobu/include/select-session.py
executable: /usr/libexec/byobu/include/select-session.py
kernel: 3.12.8-300.fc20.x86_64
runlevel: unknown
type: Python
uid: 22482

Truncated backtrace:
select-session.py:66:get_sessions:TypeError: decode() argument 1 must be string, not None

Traceback (most recent call last):
