Failed assertion when restoring files from Trash (master)
I found a reliable way to get the failed assertions described in !717 (merged), by restoring an item from the trash. Printed warning is:
** (org.gnome.Nautilus:20891): CRITICAL **: 05:30:20.757: nautilus_view_item_model_file_changed: assertion 'NAUTILUS_IS_VIEW_ITEM_MODEL (self)' failed
There also seem to be other ways, e.g. when deleting an item, but I can't always reproduce it there. It seems to be related with an item being removed from the view.
(This bug is with the current nightly version)
