It may not be the same bug in that case. However it is interesting
that the file manager appears to have crashed. Though the fact that
you say you don't want to kill it suggests that it has not crashed but
is also hung, possibly for the same reason.  What happens if you run,
in a terminal, the command

sync

If that does not complete then it is the same bug and something is
hanging onto one of the drives for some reason.  The first thing I
would do is close everything else down and kill caja. Why do you think
that might cause loss of data?  If you are worried that it was in the
middle of a move or something then copy that file or files off to USB
stick or something first using terminal commands.
