[Bug 839005] Re: software-properties-gtk crashed with UnicodeEncodeError in exists(): 'ascii' codec can't encode character u'\xe9' in position 13: ordinal not in range(128)

[der_alex1980]

This bug occurs if the path to the keyfile contains non ascii
characters, for example when importing from

/home/alex/Arbeitsfläche/keyfile.ppa.asc

which is the default Desktop directory in German Xubuntu.

Log:
