Crash when deleting opened folder via side pane

Steps to reproduce

mkdir -p tree-crash/nested/
touch tree-crash/nested/1
thunar tree-crash/
If the side pane is not visible, press Ctrl + e
Expand the tree-crash folder in the side pane to reveal the nested folder
Click on the nested folder in the side pane (or the main window) to open the folder
Right-click on the nested folder in the side pane and choose Move to Trash to trigger a crash
