Comment 5 for bug 785119

Because of this: https://bugs.launchpad.net/ntrack/+bug/785153

The issue I describe here is actually completely different to that in bug 755608 - they just both happen to occur in the context of kded4. Certainly, revision 312 doesn't fix it, although it does apparently fix bug 755608. And I'm not getting an infinite loop within any method in libntrack; it's just that poll() never blocks in the main loop.
