a couple small icon-related things:

1 when double clicking a guide to open guide dialog, i get

** (inkscape:24066): WARNING **: failed to load icon 'guide_dialog'

OK, I think I'll just remove the reference to this one.

2 launch, ctrl+n to open a new window, ctrl+q to quit:

(inkscape:24082): Gtk-CRITICAL **: gtk_size_group_remove_widget: assertion `GTK_IS_SIZE_GROUP (size_group)' failed

Jon, what about this one? It happens always when quitting with two or more windows. Moreover I got a crash which seems to be related. In a directory with many svg files (at least 6 in my case), run

inkscape *.svg

and press ctrl+q as soon as they finish loading. This gives a bunch of asserts and a crash:

(inkscape:15711): GLib-GObject-CRITICAL **: g_object_get_qdata: assertion `G_IS_OBJECT (object)' failed

Looks like some selection-changed signal callback is called right after the desktop widget is destroyed, and crashes trying to access widgets that don't exist already.
