IDLE not working for one account only

[Neil Price]

I've attached an strace of idled. It shows the bad user client 
(elangenhoven) going into idle and a message being sent to it.You can 
see the message being sent but there seems to be no reaction to it arriving.

There are a bunch of timeouts there....?
