File modified when opening

[Graziano Previato]

I have sikuly IDE 1.0.1 running on MacOSX 10.9

the procedure is the following:
def GetSeq():
    fl_seq=open('/Network/Servers/osxge1.acamarshipping.com/Users/gpreviato/src/AcroEmul/SeqRef.seq','r')
    str_seq=fl_seq.read()
    fl_seq.close()
    seq=int(str_seq)
    return seq

The file server is a MacOSX server 10.6 exporting the file inf AFP.

Before run the procedure the content of the file is:
100000

after to have run the procedure, vi shows:
1000^@^@^@

this happens after the conter touch '10000'.
Having 10000 in the file, the content is changed in 1000^@^@

Everything was OK up to 9999

I'm trying to understand...

Could be a problem on the fileserver... I'm checking...
