Ok I did run that command you requested and attempted to try and retrace my steps to see if I can replicate the bug.
Soon I clicked "Import" it reset the Xserver so I had to re-login.
The Import worked!
I ran your command with the added Log recording
***
LIBGL_DRIVERS_PATH=/nowhere f-spot > fspot-newlog

Please see attached log if that helps try and understand why the "Import" resets the Xserver.
