Well, answering both to shimi and to Martha: you are both spot on,
especially Martha - thanks!
Adding -q fixes the problem. I am inserting below the beginning and
the end of "od -c" of the zip archive for illustation.
Now, while the problem is fixed I am not satisfied yet:
1) I have never had to add -q before: zip/unzip have always worked
fine. Why now? The man page does not say anything really
2) It is my script that calls zip - it is not called by logrotate or
anything: why piping from cat or gunzip (used by logrtate) works
fine but piping from logrotate somehow causes the problem? Note
also that the script does not zip stdin directly - it zips a file.
The output of "od -c" follows (sorstdout.log is the actual name of the
log file rotated by logrotate).
