Thanks! I was having problems too and this solved it. Mine was, for the sake of web searches:

File "/usr/bin/calibre", line 20, in <module>
sys.exit(calibre())
File "/usr/lib/calibre/calibre/gui_launch.py", line 73, in calibre
main(args)
File "/usr/lib/calibre/calibre/gui2/main.py", line 543, in main
listener = create_listener()
File "/usr/lib/calibre/calibre/gui2/main.py", line 514, in create_listener
return Listener(address=gui_socket_address())
File "/usr/lib/calibre/calibre/utils/ipc/server.py", line 110, in __init__
self._listener._unlink.cancel()
AttributeError: 'NoneType' object has no attribute 'cancel'
