I’m trying to fix a drag/drop fault on a PyGTK application.
On the very first drag, I get the following warning on the console:
GtkWarning: gtk_tree_view_drag_begin: assertion `path != NULL' failed
This seems to be benign – AFAICT, the drag works – but it’s frightening the horse, and I’d like to fix it.
Can anyone point me at some details of what this path is and how I go about making sure it isn’t null?
