mod_perl and Filter-Crypto

Hi everybody! I'm trying to use Filter-Crypto with mod_perl but with poor results. Everything works fine until I enable mod_perl. After this I'm getting errors like: "Unrecognized character \\x1F at ...". The line where it points is the begining of the encrypted part of file. Filter-Crypto change
