euca-authorize and euca-revoke throws unknown error for invalid port range

Using boto 2.0, this doesn't seem to reach nova and returns a less than desirable error. Therefore opening a boto task, as this should be resolved with both client and server.

$ euca-authorize -P tcp -p -222222 -s 0.0.0.0/0 default
Traceback (most recent call last):
  File "/usr/bin/euca-authorize", line 198, in <module>
    main()
  File "/usr/bin/euca-authorize", line 112, in main
    from_port = int(ports[0])
ValueError: invalid literal for int() with base 10: ''

$ euca-revoke -P tcp -p -222222 -s 0.0.0.0/0 default
Traceback (most recent call last):
  File "/usr/bin/euca-revoke", line 201, in <module>
    main()
  File "/usr/bin/euca-revoke", line 111, in main
    from_port = int(ports[0])
ValueError: invalid literal for int() with base 10: ''

Ah, i copied and pasted the entry from the description which contained a "-" infront of the port. This is obviously invalid syntax.

With correct syntax, it does indeed return as described:
$ euca-authorize -P tcp -p 222222 -s 0.0.0.0/0 default
default None None tcp 222222 222222 0.0.0.0/0
