NB: this is on i386 XEN3PAE_DOMU

Another problem: even with no rule loaded (empty ipf.conf and
ipnat.conf), ipfilter corrupts outgoing packets:

03:40:01.561169 IP truncated-ip - 3 bytes missing! 192.0.2.14.65439 >
192.0.2.20.53: 15689+[|domain]

Depending on the original length, the packet is truncated of 1 to 3
bytes. The behavior vanishes as soon as I run ipf -D 

Anyone experienced something similar?
