I wonder if this could possibly be due to the same thing that caused

Subject: [Bug] Output of too many evaluations cause strange behavior
http://news.povray.org/3bc215b3@news.povray.org

It looks like too much output to the message pane causes the pane to
clear and other strange behaviour. It's as if the program doesn't notice
that it's filled the space allocated for the text for that pane, and is
scribbling over the next chunk of memory.

Did you, by any chance, have an "evaluate" statement in your animation?
Marc-Hendrik's non-animated scene had 150 "evaluate"s in it, which
caused a large amount of message output.
