On two different computers, Inkscape sometimes crashes with the following error messages:
(inkscape:2536): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkBin'
(inkscape:2536): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkBin'
(inkscape:2536): GLib-GObject-WARNING **: invalid cast from `GtkLabel' to `GtkBin'
[...]
Segmentation fault (core dumped)
I googled the error messages but could not find any satisfying answers. Any ideas?
