g-action: No applicable method: G-BOXED-OPAQUE-POINTER

[Ambrevar]

I'd like to create a GAction: https://developer.gnome.org/gio/stable/GSimpleAction.html

I did this:

(gio:g-simple-action-new  "foo" glib:+g-variant-type-any+ )

which raised

There is no applicable method for the generic function
  #<STANDARD-GENERIC-FUNCTION GOBJECT::G-BOXED-OPAQUE-POINTER (1)>
when called with arguments
  ("*").
   [Condition of type SB-PCL::NO-APPLICABLE-METHOD-ERROR]

Backtrace:

Am I doing something wrong? Bug?

Should be (gio:g-simple-action-new "foo" (glib:g-variant-type-new glib:+g-variant-type-any+)) I think.

This works indeed, thanks!
