Application: konqueror (4.14.13)
KDE Platform Version: 4.14.32
Qt Version: 4.8.7
Operating System: Linux 4.4.88 x86_64
Distribution (Platform): Slackware Packages

-- Information about the crash:
- What I was doing when the application crashed:
I had a few browser tabs open and one tab pointed to a .tar.gz, since I was interesting in downloading a package.  When I try to close this particular tab, Konqueror crashes.  This occurs every single time without fail (I've tried maybe 6 or 7 times now).

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
