Sending complex parameters via signals

[Steve Kreyer]

Hi!

I'm using the dbus-glib-binding. I want to send signals on the bus which 
should have parameters with complex types, such as "ai" or "a(yyysssi)". 
Is it possible to send such parameters over signals? I've tried it in 
several ways, but none of them worked.
For example trying to register the signal on the object side with a 
G_TYPE_BOXED parameter with the appropriate marshaller, I get the 
following error during "signal register time":
-----
(process:15926): GLib-GObject-WARNING **: gsignal.c:1270: parameter 2 of 
type `GBoxed' for signal "AuxinPlayer::time_position__status" is not a 
value type
-----
And registering the signal on the object side with a G_TYPE_OBJECT 
parameter results in this error during "signal emit time":
-----
(process:15885): GLib-GObject-CRITICAL **: g_value_type_compatible: 
assertion `G_TYPE_IS_VALUE (src_type)' failed

(process:15885): GLib-GObject-WARNING **: gsignal.c:2180: invalid object 
type `
-----

If this is not the right list for this issue please let me know :-)

Any help on this problem would be appreciated.

TIA,
Steve
