Crashes at startup

[Damien@…]

Defaults variants are "+ipv6 +quartz +no_x11 -x11 +nls +tls +ssl +with_default_names +ares +idn +aqua +bash_completion +adns +aspell " on iMacIntel.

In X11.app (2.4), from a terminal :

$ port installed | grep inkscape
  inkscape-devel @0.46.22157_0+no_x11 (active)

$ inkscape 

(inkscape:83509): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed

(inkscape:83509): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed
2009-10-12 13:34:27.894 inkscape[83509:903] InjectEventHandler

At this point, inkscape is ready to be used (the interface is displayed on the screen)

But when clicking anywhere in inkscape makes a window appear, saying "Inkscape a subi une erreur inter et va se fermer maintenant". And in the terminal, the following is written:

Emergency save activated!
Emergency save completed. Inkscape will close now.
