>From the main menu I go to  changes | recently logged changes.  This
produces a change list sorter.

When I selected all and filed in the changes, I got repeated errors at
the boundaries, like this:

Am I misunderstanding how this is supposed to work, or is something
broken?

3.1alpha #4173 image.

I'm running on Linux, although I think I was on Win32 when my image
got damaged (I think only part of the file got saved, so I'm
recovering from an older one).

P.S.  squeak -memory gets more memory on Linux, at least my version of
the VM (Debian).
