Bug 343311

Application: konqueror (4.14.3)
KDE Platform Version: 4.14.3
Qt Version: 4.8.6
Operating System: Linux 3.16.7-7-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

I clicked on an http link to a .docx file in kmail, which points to our sharepoint server.
konqueror opened and showed the ark part.
While loading (e.g. at 50%) I closed the window as I do not want the docx in ark...

Then the crash appeared.
I can reproduce it always.

The crash can be reproduced every time.

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