Bug 421820

Application: konqueror (5.0.97)

Qt Version: 5.9.7
Frameworks Version: 5.55.0
Operating System: Linux 4.12.14-lp151.28.48-default x86_64
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:
I tried to open an HTML document, that was located on a local server (not public) from the history.
I was served with the Open with other application or download dialog. 
Upon pressing cancle that dialog closes, the address bar becomes grey (inactive) and after some seconds konquerror crashes.

The crash can be reproduced every time.

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