Bug 324097

I was changing KDE Plasma Desktops theme, I click "Get new themes" and it opened up rekonq to opendesktop.org to a themes download page, I then clicked the download button and it crashed. I tried twice more and both times it crashed when I licked download.

Reproducible: Always

Steps to Reproduce:
1. Open KDE desktop themes and click "Get new themes".
2. Click on a theme that will open Rekonq (only some open browser) to a theme download page @ openddesktop.org.
3.  Find file download button and click.
Actual Results:  
When download button is clicked Rekonq automaatically crashes.

Expected Results:  
It should have allowed me to download the file. I copied download page link and pasted into Firefox and it didn't crash.

Application: rekonq (0.9.1)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.5.0-39-generic x86_64
Distribution: Ubuntu 12.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was changing KDE Plasma Desktops theme, I click "Get new themes" and it opened up rekonq to openbox.org to a themes download page, I then clicked the download button and it crashed. I tried twice more and both times it crashed when I licked download.

The crash can be reproduced some of the time.
