Bug 115963

Version:           3.2.1 (using KDE KDE 3.4.2)
Installed from:    Fedora RPMs
OS:                Linux

I can reproduce this 100% of the time.

1- Open a KDevelop project
2- Ctrl-Alt-F (Find in files), and search for a string that appears in many files
3- Undock the "Find in files" dock widget
4- Click on one of the finds in the "Find in files" dock widget
5- Close all the open files in KDevelop with the little red X by the tabs
6- Click on one of the finds in the "Find in files" dock widget
Result : Crash
