I got this error too, but I do not know much about DBus and didn't have the time to look into it yet. my workaround was:
kill gwibber and gwibber service purge debian gwibber package go to gwibber working copy python setup.py bdist su -c 'python setup.py install --install-layout=deb' of course this will install files that apt/dpkg do not know about. regards -- You received this bug notification because you are a member of Gwibber Bug Heros, which is subscribed to Gwibber. https://bugs.launchpad.net/bugs/702191 Title: Can't run Gwibber 2.32 under Debian Squeeze Status in Gwibber: New Bug description: I've just built Gwibber 2.32 under Debian Squeeze, but everytime I try to run it, I get this error: ----------------------------8<---------------------------- brunomiguel@fringe:~$ /usr/src/gwibber-2.32/bin/gwibber -d ERROR:dbus.proxies:Introspect error on com.Gwibber.Service:/com/gwibber/Service: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name com.Gwibber.Service was not provided by any .service files Traceback (most recent call last): File "/usr/src/gwibber-2.32/bin/gwibber", line 72, in <module> client.Client() File "/usr/src/gwibber-2.32/gwibber/client.py", line 548, in __init__ self.w = GwibberClient() File "/usr/src/gwibber-2.32/gwibber/client.py", line 34, in __init__ self.model = gwui.Model() File "/usr/src/gwibber-2.32/gwibber/gwui.py", line 42, in __init__ self.services = json.loads(self.daemon.GetServices()) File "/usr/lib/pymodules/python2.6/dbus/proxies.py", line 68, in __call__ return self._proxy_method(*args, **keywords) File "/usr/lib/pymodules/python2.6/dbus/proxies.py", line 140, in __call__ **keywords) File "/usr/lib/pymodules/python2.6/dbus/connection.py", line 630, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name com.Gwibber.Service was not provided by any .service files Exception AttributeError: "'NoneType' object has no attribute 'px_proxy_factory_free'" in <bound method ProxyFactory.__del__ of <libproxy.ProxyFactory object at 0x92351ac>> ignored ----------------------------8<---------------------------- According to the information on INSTALL file, I have met all dependencies.
