The kernel log says all!
I have 2 laptops showing the messages, both amd64.
One of them runs a 32-bit system in a VM with the linux-image-3.3.0-rc6-686-pae kernel,
that does not have this problem.
The amd64 kernel from unstable (3.2.0-2) does not show the messages.

The code that generates this warning (nla_parse()) has not changed
between 3.2 and 3.3-rc6, so this is probably due to a difference
elsewhere.  It seems to indicate a bug in the userland program sending
the message that is being parsed, but perhaps I misunderstand.

It would be useful if we could tell which program is sending the
message, but I think that may be difficult to do.

Life would be so much easier if we could look at the source code.

Some further investigation showed that the 1st occurrence of the message 
is related to the start of KDE. After stopping X (and KDE) there are no 
new messages logged.
