The Locate dialog is never destroyed (therefore its destructor (~LocateDlg) can't be used because it's never called , etc.), the present change can solve that.

This is a screenshot of a Valgrind report inside Qt Creator:

~LocateDlg()
{
    QTextStream(stdout) << "DESTRUCTING" << endl;
}

he sees that that code is never executed.

Execute Krusader, launch the Locate dialog, sometimes close the Locate dialog, close Krusader.

Valgrind may be used, and a destructor like

~LocateDlg()
{
    QTextStream(stdout) << "DESTRUCTING" << endl;
}

can be added in order to know when the Locate dialog is really destroyed.
