Probably caused by QIcon not being threadsafe
Comment 2 Marco Richetta 2019-02-19 13:54:53 UTC 
I think something inolving threads is not junior-friendly but if there is any way, I'm willing to help.
Comment 3 Christoph Feck 2019-03-09 16:17:03 UTC 
If you do not use the 'appstream' runner, you can disable it in krunner plugin configuration to avoid this crash.
