I see a Thunar process for the directory in question:
ps ax | grep -i thun
230091 ? Sl 0:00 /usr/bin/Thunar file:///home/<redacted>/Desktop/<redacted>
Which is created immediately when I click on the icon. After the delay, the window appears (but is unresponsive). At that time I still only have the one Thunar process. After another delay, the window becomes responsive (still only one process).
At this point, I can click on other icons on the desktop and get a window immediately (still only one process), but the windows are unresponsive for the same delay.
Closing all windows, shutting down Thunar, and re-running puts me back to the beginning state of no window for a delay, and then unresponsive for a delay.
