Comment 46 for bug 44196

Thanks Johnathon, that's a useful comment.

I also found this from debian :

Disabling gnome-cups-icon
=========================

 On large networks, with shared CUPS servers, it might be desirable not to
 start the gnome-cups-icon which regularly polls the CUPS server for the
 status of jobs.

 gnome-cups-icon is launched by gnome-session by default, but this is
 configurable via gnome-session-properties.

gnome says that it's a cupsys problem. It's true, but this is not a reason to not fix the client part.
Even a malfunctionned server should lead a client to eat all cpu, isn't it ?
