com.mikeasoft.cutespotify app tried to create an illegal directory under Qt5.2

When comparing Qt5.0 denials with Qt5.2 denials from test runs that popey did, it looks like com.mikeasoft.cutespotify somehow got a bad directory under Qt5.2:

Decoded: /opt/click.ubuntu.com/com.mikeasoft.cutespotify/1.3.1//

(note, there is a UTF-8 character between the '//'). Confirmed that launching under Qt5.0 does not have this behavior (though, I do not have a CuteSpotify account, so only started the application).
