Hi,

to fix it.
If anyone has an idea about the problem !!

I had the same problem. I've tried to fix with the following patch.
Could anybody from the develop team check this patch?

Hi,

we want to take care of this problem. Is it possible that you send the
pcap to us that caused the segmentation fault?

Regards, Katrin

Hi,

a possible crash in the gnutella detection has been identified. The fix
for this issue was committed to the SVN repository and a patch based on
OpenDPI 1.1.1 is attached to this mail.

Best regards,
Martin
