Re: GUPnP.ServiceProxy.send_action_hash() invalid parameters

[Jens Georg <mail jensge org>]

Hi,

Unfortunately that's a bug in GUPnP that prevents its usage with GI.
sorry about that.

We have no clear solution for that currently.

(Also, please don't use send_hash, it's broken and cannot be fixed)
