Thunar's "Open Terminal here" bug

I'm using Thunar 1.8.2 on Debian Testing and the "Open Terminal here" function seems buggy. I've set up the custom action xfce4-terminal --working-directory=%f with the keyboard shortcut F4. Oddly enough, right-click in Thunar and "Open Terminal here" always seems to work. That opens the xfce4-terminal with the current working directory. But with F4 it always opens the terminal with the directory I last used the right-click "Open Terminal here". So for example, in Thunar I go to /tmp/, right-click, "Open Terminal here", I get a Terminal with /tmp/ as the current working directory. I close the terminal, move to /home/ in Thunar, then press F4 and I get a Terminal with /tmp/ as the current working directory again. How do I fix this behavior? *edit:* This is the current configuration:
