Bug 346149

Application: konqueror (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.0 (jessie)

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

My bank's web site shows bank statements as a PDF in a new window.  I have Konqui configured to open such links in a new tab of the current window.

I can open, view and close one statement OK and it returns to the main window OK.  When I click on the link which should open the second statement, Konqui crashes instead.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
