Bug 379176

Application: konqueror (4.14.26)
KDE Platform Version: 4.14.26
Qt Version: 4.8.7
Operating System: Linux 4.1.34-33-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
Opening pages like getemoji.com, emojipedia.org and the like causes a crash.
I could not find a page with lots of emojis that konqueror could open.

The crash can be reproduced every time.

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