[Bug 1092390] Re: kded4 memory use grows with every accepted ssh connection. Memory leak?

[David H]

OK, I stopped all services in the service manager.  Right now, each
service has its "stop" button greyed out with only the "Start" button
active.

I switched on kdebugdialog for kded4. There's a bit of chatter as kded4 starts up, but nothing while the sshs are happening. See attachment.
