Comment 3 Dimitris Kardarakos 2015-12-03 11:12:03 UTC 
I managed to bypass this crash by moving /usr/share/parley/plugins/google_images.desktop to /usr/share/parley/plugins/google_images.desktop.bak.
Comment 4 Dimitris Kardarakos 2015-12-31 10:56:12 UTC 
Cannot reproduce anymore in Plasma 5.5.1 / Frameworks 5.17 (archlinux packages)
