Comment 5 for bug 20149

A similar bug already occurred in Debian and was fixed with a new upstream
version. I tried hard, but I cannot reproduce the bug (I deleted the devices,
and so on). I also tried to add a simple patch that drops invalid devices, but
it doesn't work so far.

Can you please download

  http://people.ubuntu.com/~pitti/packages/pbbuttonsd_0.7.1-1ubuntu1_powerpc.deb

install it with

  sudo dpkg -i pbbuttonsd_0.7.1-1ubuntu1_powerpc.deb

and check whether it works then? If so, I will try to isolate the patch and
backport it to our current version.
