Comment 1 Andrius Štikonas 2016-04-19 11:56:03 UTC 
It works for me with frameworks 5.21 (KPMcore 2.1). No crash here. Could you please try with newer frameworks (I think Kubuntu will have an upgrade soon)
Comment 2 Andrius Štikonas 2016-04-19 11:58:08 UTC 
Hi Alex,

Does this sound like something that was fixed recently in kded5?

Regards,
Andrius
