Changing from compact view to list view or vice versa or pressing F5 in a directory containing many files freezes thunar

Follow-up to #1315 (comment 87110)

I tested this in a directory containing 20,000 images. Once the view has been changed, the cursor rotates indefinitely, thunar does something (given the cpu usage), and closing the window brings up the force close dialog.
