I still receive a CRC error on the attached file:

$ unzip -t
error []: missing 1 bytes in zipfile
  (attempting to process anyway)
error []: attempt to seek before beginning of zipfile
  (please check that you have transferred or created the zipfile in the
  appropriate BINARY mode and that you have compiled UnZip properly)

    testing: xxxxxxxr.fmb OK
    testing: RZP_IZRACUN_PZZ.pks OK
    testing: RZP_IZRACUN_PZZ.pkb OK
    testing: naslov.txt bad CRC 691786f0 (should be ade8a8dd)
file #7: bad zipfile offset (local header sig): 110845
  (attempting to re-compensate)
    testing: MG_NS-0544-2008.lst OK
At least one error was detected in

This may be an artifact of using Outlook/renaming the file to .txt...

Hrm... when run via your shell, is it calling the same unzip program that incron is calling?

One thing I noticed---are you sure you want incron to use the IN_CREATE event? incron may be calling your scripts before the file has finished writing (hence the incomplete zip file error).

Try IN_CLOSE_WRITE. This event will cause incron to act only when a file being watched has finished writing.
