Erroneous UDP packet?

Hello,

the gnunetd crashes after a couple of minutes on my linux box. This seems to 
be related to recieving an erroneous UDP packet, because gnunet is dead rigth 
after the kernel signals:

... kernel: UDP: bad checksum. From 66.0.20.109:32877 to <myIP>:2086 ulen 1480

Regards,
Thomas


PS:

Sorry for not using mantis, but I receive an SMTP error message transmitted by 
HTTP after requesting a password:

>PROBLEMS SENDING MAIL TO: 
>Mailer Error: SMTP Error: The following recipients failed.

(Yes, the email address I used was valid.)
