Problem with write file command to desfire card EV1

[GoogleCodeExporter]

What steps will reproduce the problem?
I create a file and trying to write some data to this file. I could see that 
the data to card for write command (Length:38): 0x=3d 0f 00 00 00 1e 00 00 53 
6f 6d 65 20 64 61 74 61 20 74 6f 20 77 72 69 74 65 20 74 6f 20 74 68 65 20 63 
61 72 64 -- ("Some data to write to the card") is proper but the error is 
always 7e (Invalid command string length). I also get the same error message 
for read file command read_cmd(Length:8):  0x=bd 0f 00 00 00 00 00 00 

What is the expected output? What do you see instead?
response to be 0x00 but its always 0x7e

What version of the product are you using? On what operating system?
Windows

Please provide any additional information below.
Should we authenticate for write file command immediately after creating the 
file?

Err… wait… is this a libfreefare problem or is it completely unrelated to 
nfc-tools?

If the problem is with libfreefare, please attach a sample source code that 
triggers the problem, otherwise sorry, but here is not the place to get help to 
get your code fixed…

If you are "skay" from this post:

I remind you that the topic was about libfreefare, so I assumed you whre using 
it.

Thanks!
