#478 Ctrl-Shift-PgUp or Home in Interactions Pane
I can't exactly reproduce this, but quite often when I
press Ctrl-Shift-PgUp or Ctrl-Shift-Home in the
Interactions Pane, I get the exception below. Sometimes
it even puts the pane in an inconsistent state that
causes several errors per second.

I will look at this. As a stopgap, we can at least catch
the exception and repair the reduced model.

I'm not able to reproduce this anymore, so it seems like
Adam fixed this issue.
