Comment(by Phil):

 I've started on a script to clean up extraneous entries, except that it
 doesn't work.

 The reason it doesn't work is that there are preview images in the
 datastore for objects that have no matching file in the datastore itself.
 I assume that's because they are solely database entries, with no matching
 saved file.

 That's a shame, as it means this program would have to dig into that
 database to determine just what it can and cannot purge.

 For safety reasons, I'm not attaching the script to this bug entry, but it
 can be found at [http://dev.laptop.org/git/users/phil/support-scripts/]
 along with other stuff I've written.  It's 'purge-journal', and by default
 won't do anything; you have to '--force' it to run.

 This is obviously a stopgap until the actual bug is fixed, and since it
 doesn't behave properly it's a poor stopgap, but it might be a start for
 something else.
