On Fedora Core 4 services browser causes high CPU usage. This looks like an infinitive loop because gajim does not respond. On Rawhide (Fedora Cores development tree) everything works fine.
How to reporoduce:
From Action menu choose "Discover Services".
Unfortunately, I don't know how to provide more useful data. How should I debug this? I would like to fix it because users start to complain ;-)
