I have the same issue for versions 0.81.2-0.81.4.
software-properties-gtk crashed with UnicodeDecodeError in init_distro(): 'ascii' codec can't decode byte 0xc3 in position 13: ordinal not in range(128)
It seems to be an ascii vs unicode issue introduced in version 0.81.2
A workaround atm is to downgrade to version 0.80.13.
