Thunar freezes if you choose "View --> Side Panel --> Tree"

Thunar freezes if you choose "View --> Side Panel --> Tree" option menu. It can be reproduced in Guest account too. If you close Thunar and open again, it freezes again. It's necessary delete "last-side-pane" String in Setting Editor (Xfconf) to Thunar returns to normal.

Apport does not repport anything about this issue.
