Bug#977124: crashes with "NameError: name 'unicode' is not defined"

[Philipp Marek <philipp@marek.priv.at>]

Package: qtqr
Version: 2.0~bzr33-2
Severity: normal
X-Debbugs-Cc: philipp@marek.priv.at


When trying to copy/paste an URL, or sometimes even when just typing, 
qtqr crashes with

    Traceback (most recent call last):
      File "/usr/bin/qtqr", line 568, in qrencode
        unicode(self.tr('Bad input')),
    NameError: name 'unicode' is not defined
    Abgebrochen

I could use it only once in 10 tries or so, it's nearly unusable.
