A simple sample html file that can induce a crash

Version:           unspecified
OS:                Linux

Using Krusader version 2.0.0 and KDE 4.4.4 (there are no options for these versions yet in the relevant drop-down menus so I couldn't specify it there)

Krusader crashes with Signal 11: Segmentation Fault when closing with ALT+F4 or CTRL+Q an HTML file opened from the hard drive in KrViewer.
For this crash to happen, is necessary and sufficient that the html file contains a <head> tag - therefore it happens with almost all html files.

Interestingly, it does NOT crash if:

- Doesn't crash if the html file is closed by pressing ESC, or clicking the X button with the mouse to close the window, or by clicking "Quit" with the mouse from the KrViewer menu.
- I have only seen the crash with html files, i.e. it does not crash when closing with ALT+F4 or CTRL+Q a KrViewer window that has a .txt file open for example.
- It doesn't crash when closing an html file that doesn't have a <head> tag.

Reproducible: Always

Steps to Reproduce:
1. Create an .html file containing a <head> element. A file containing only a single <head> element is sufficient to make it crash. Alternatively, download any html file from the internet, e.g.: http://en.wikipedia.org/

2. Open it in KrViewer (by pressing F3 in Krusader)

3. Press either ALT+F4 or CTRL+Q attempting to close the KrViewer window

Actual Results:  
Krusader crashes with Signal: 11 (Segmentation fault)

Expected Results:  
Close the KrViewer window and return to Krusader

Application: Krusader (krusader), signal: Segmentation fault

Is it reproducible in > 2.3. beta1 and a recent kde version ?
