Problems with GHashTable in signal handler

[Jörn Reder <joern zyn de>]

Hi,

I try to use the "create-plugin-widget" signal of Gtk2::WebKit::WebView,
which passes a GHashTable to the callback. Here it's signature from the
docs:

  GtkWidget* user_function (WebKitWebView *web_view,
                            gchar         *mime_type,
                            gchar         *uri,
                            GHashTable    *param,
                            gpointer       user_data) : Run Last / Action

  (from http://webkitgtk.org/reference/webkitgtk-WebKitWebView.html#WebKitWebView-create-plugin-widget )

Perl dies with this error message when my signal handler is called:

  GType GHashTable (146176672) is not registered with gperl

Since signal handling is completely covered on Glib level I don't think
this problem is related to Gtk2::WebKit. The Glib perldoc says 
GHashTable is bound to the native Perl hash datatype. I grep'ed the 
sources of Glib and Gtk2 to find any examples of passing GHashTables to
Perl - with no luck.

Any help on this is appreciated ;)

I am using Perl 5.10.1 and these module versions on Debian sid:

  Glib::VERSION         = 1.222
  Gtk2::VERSION         = 1.221
  Gtk2::WebKit::VERSION = 0.06

Thanks,

Jörn
