Application: plasmashell (5.8.2) Qt Version: 5.7.0 Frameworks Version: 5.27.0 Operating System: Linux 4.8.4-1-ARCH x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: Tried adding the comic strip widget. On the left top corner, i clicked on Add Widgets, picked the comic strip and dragged it to my desktop. Doing that crashes plasma every time. Tried with other widgets, they work. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

can this be reproduced with more debug symbols for kdeplasma-addons and plasma-framework?
if that crash is at line 95 of comic.cpp, it means the applet is correctly installed, the comic dataengine not (weird package split by the distro?) existence of that engine should be guarded against anyways

moved as downstream, as we don't crash anymore, but the dataengine missing tells that the distribution didn't package it correctly and probably splitted the kdeplasma-addons repository in multiple packages, but didn't set the dataengine as a dependency of the applet
