rsync fails to retrieve file (if local file is incorrect)

[nvbolhuis at aimvalley.nl]

I'm using rsync on an embedded powerpc platform
with flash filesystem.
Because of a power-cycle a local file got corrupted.
This file is /flashfs/isd1, it has the correct size but
wrong MD5SUM (cd5...).

Using rsync to retrieve the right file (from a remote machine)
fails!
If I delete the file first, it works (see below).
How is this possible ?
