Bug Description

When I run the "System Load Monitor" under xfce4, the XOrg process starts using about 60% of a CPU. When I remove the System Load Monitor from the panel, this stops. This is repeatable: whenever I start the applet, the high CPU usage returns.

Thanks for the quick reply.

Both releases shipped with the exact same package version, so it is not quite clear what change has fixed this bug.
