Summary: shoppingcart kills freevo (patch)

Initial Comment:
hi, 

if I use the shoppingcart to move a file from one folder to another folder, it does, but immediately the GUI dies ; the traceback is

Exception caught in main loop

Message:
hi, it seems it is some kind of race condition ; the patch addresses the
problem

BTW if the race happens , it should log an error; but curiously after I
added the patch, I did not (yet) see the error, maybe the fact that the
code is some lines longer is enough to avoid the race
