SKB BUG: Invalid truesize (412) len=28, ipsec related ?

vanilla 2.6.25.13, working as a router, 4 interfaces about 100MBit/s traffic
using e1000 and tg3 ethernet drivers

it's a production machine so I basicly can't touch it now, I think
it's triggerd by ipsec tunnel because
before rolling this machine on production it was stress tested
(without the tunnel) to tune the firewall,
and there ware no BUG()'s triggerd.

tunnel is created by setkey
add 10.0.5.2 10.0.5.1 esp 0xxxx -m tunnel -E 3des-cbc ...

Tomorrow i will try to trigger it in a test environment, any pointers
how to get more info out of it?
I found this http://lists.openwall.net/netdev/2008/05/06/61 will it be ok ?
