Comment 13 for bug 1170998

Maybe this issue has to do with the encoding of the strings passed by those applications.

PLEASE TEST THE FOLLOWING BRANCH. STEPS:

$ sudo rm /usr/local/bin/wingpanel # Make sure no local versions of wingpanel are installed, since these override the binary from the package
$ sudo apt-get install elementary-testing-scripts
$ elementary-install-from-bzr lp:wingpanel lp:~elementary-apps/wingpanel/tweaks
$ killall wingpanel # Cerbere will restart wingpanel and will use the updated version
