If the original binary file wasn't marked as such in CVS (with the -kb)
flags, then you were sitting on a time-bomb all along. CVS could have
corrupted the file at any time. There's no bug in cvs2svn here; if a
file doesn't have -kb flags in CVS, then cvs2svn assumes it's a
textfile and applies the 'svn:eol-style=natve' and 'svn:keywords'
properties to the file, which definitely change the file contents. If
the file is binary, then this will very likely corrupt the file.
Again, not a bug. It's because you didn't have the file marked as
binary in CVS.
If you have more questions, please mail firstname.lastname@example.org, it's
a separate project and separate mailing list.

No, this is an expected effect of the svn:eol-style and svn:keywords
properties being 'detranslated' when you run 'svn diff' and 'svn
To solve your problem, remove those two properties, then commit. Then
overwrite the file with the good one, and set 'svn:mime-type' to
'application/x-octet-stream' or some other non-text type.
Alternately, you can simply 'svn rm' the old file, and 'svn add' the
