AW: corrupted rev file transforming from Win to Mac

[Tiemo Hollmann TB]

Seeing no comments on my topic, helps me to believe that I experienced a
really seldom problem, which I hopefully won't encounter twice.
Actually I even don't know what was really going on with my file. The
explanations where just a theory, which I can't reproduce.

Thanks
Tiemo
