try the following:

md5sum /bin/gzip
scp goodserver:/bin/gzip /bin/gzip
md5sum /bin/gzip
ls /bin/gzip
md5sum /bin/gzip

can you send the output?

i had the same problem on a few servers, every file was bigger before
the ls, but still worked.
beside gzip, it segfaultet.
you can also strace ls, normally ls does nothing in /proc, but this ls
had done anything in /proc.

But where is it from?
Have you installed/executed any binarys beside debian-packages?
