Bug 366354

Application: krunner (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.27-27-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: Within the comic widget, pressed the back button to view the previous PHD Comics strip.  Plasmashell then crashed.  Happens every time.  Most other comics available for the widget don't work at all and/or crash plasmashell.  The one exception to all of this is Dilbert; it rarely crashes the plasmashell.

The crash can be reproduced every time.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
