libktcore/dbus/dbusgroup.cpp:66 - path == "/group/интернет"
QDBusConnection::registerObject check path and fail if any non ascii char in the path.

It seems that the dbus spec only allows [A-Z][a-z][0-9]_

Will have to find something against this.

OK, in a situation like, we will now use group_X where X is a number for the dbus path
