Bug 349777

Application: konqueror (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.7
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:

I had 4 webpages open; three internal.
External page:
http://ftp.gnome.org/pub/GNOME/sources/msitools/0.94/

From the external page I clicked the msitools-0.94.tar.xz link: http://ftp.gnome.org/pub/GNOME/sources/msitools/0.94/msitools-0.94.tar.xz

The ark-part loaded the archive and I could expand folders and view files within the archive, but when I attempted to return to the previous page, konqueror crashed. The list of previous pages could be viewed without a crash.

The crash can be reproduced every time.

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