This shows the benefits of 'xmode verbose' :) There's enough info in
that traceback to understand the problem:

This is the call that fails. To confirm this is the problem, try:
shutil.move('/tmp/foo','/fat32partition/foo')
With any valid /tmp/foo file and your actual path to your fat32
partition. If this also fails, it's because this copystat() call

which in turn tries to call utime():

is somehow not OK for fat32 partitions, or because you don't have the
right permissions on your system.
You need to be sure that you have your fat32 partition mounted with
the right user permissions, otherwise things like these can fail.
At this point, it's not yet clear if this is a problem with backend_ps
in mpl or your permissions configuration.
