terminator may crash during start on 32bit system due to invalid dus-name

[Andreas Bleischwitz]

terminator crashes on start:

[andreas]~% terminator
ConfigBase::load: Unable to open /home/andreas/.config/terminator/config ([Errno 2] No such file or directory: '/home/andreas/.config/terminator/config')
BUS_NAME: net.tenshu.Terminator2-0x21012a2c
Traceback (most recent call last):

    @dbus.service.method(BUS_NAME, in_signature='a{ss}')
  File "/usr/lib/python2.7/site-packages/dbus/decorators.py", line 155, in method
    validate_interface_name(dbus_interface)
ValueError: Invalid interface or error name 'net.tenshu.Terminator2-0x21012a2c': contains invalid character '-'

Further investigations showed that the calculation for the DBus-interface may result in a negative number due to the use of hash().
