Message validation fails

[Julian Stecklina]

Hello,

I have begun hacking on a dbus implementation in Common Lisp and am
currently stuck with the following issue. After successfully
authenticating to the daemon, my client tries to send a Hello message
which is rejected by the daemon.

Debug output from dbus-daemon is:

14201:  128 unused bytes sent to message loader
14201: have 128 bytes, need body 0 + header 128 = 128
14201: validating body from pos 0 len 128 sig 'yyyyuua(yv)'
14201: Failed to load header for new message code 40

Can anyone spot what I might have done wrong?

Well, take it from an old hand: the only reason it would be easier to
program in C is that you can't easily express complex problems in C,
so you don't. - Erik Naggum (in comp.lang.lisp)
