            Bug ID: 340193
           Summary: Konqueror crashed when clicking in window.
           Product: konqueror
           Version: 4.13.3
          Platform: Mint (Ubuntu based)
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: file list view
          Assignee: konq-bugs@kde.org
          Reporter: agander93@gmail.com

- What I was doing when the application crashed:

I already had a Konqueror window open, and I deleted some content from the
location bar, to leave just /home/aga.  The usual drop-down appeared, but I
wanted instead to view the whole folder.  So, I clicked in the body of the
window, outside of the drop-down.

Konqueror crashed, each time I tried this.

The crash can be reproduced every time.

Reproducible: Always

Steps to Reproduce:
1. Select an open Konqueror window.
2. Remove part of the location bar content to leave just your home folder
address displayed.
3. When the drop-down appears, ignore it and click elsewhere in the Konqueror
window.
4. A crash occurs.

Actual Results:  
Crash.

Expected Results:  
My home folder content should be displayed.

Application: konqueror (4.13.3)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic i686
Distribution: Linux Mint 17 Qiana (KDE)
