Comment 33 for bug 203217

I'm still getting high CPU usage after a few hours of usage.

The system is using LDAP with just 5 users right now as It is a developmnet environment. In production there will be hundreds of users.

strace shows an infinite print:

strace -p `pidof fast-user-switch-applet`
