The following simple example used to work in the gsoc dbus branch. It no longer works in the branch, and doesnt work with a dbus enabled trunk build either.
(defun inkscape-test ()
"Opens inkscape, draws a black rectangle. a dbus compatible
Inkscape needs to be running 1st."
(let*
((desktop (dbus-call-method
:session "org.inkscape" "/org/inkscape/application"
"org.inkscape.application" "document_new" ))
(rect (dbus-call-method
:session "org.inkscape" desktop
"org.inkscape.document" "rectangle" :int32 100 :int32 100 :int32 100 :int32 100))
)))
backtrace:
** (inkscape:20564): CRITICAL **: SPDocument* sp_desktop_document(const SPDesktop*): assertion `desktop != NULL' failed

What has changed since? Do you remember after which revision (merge from trunk) things stopped working in the branch or a date (time frame)? bazaar. launchpad. net/~inkscape. dev/inkscape/ gsoc2009_ api/changes>
<http://
Also, could you please add information about your platform?
Which versions of dbus/dbus-glib bindings/glib did and do you have installed?
