Patch to fix Windows specific code, you can see that the condition in the while
loop is pretty weak and can lead to an infinite loop if the result of
'url.upUrl()' is 'url'

Version:           unspecified (using KDE 4.7.4) 
OS:                MS Windows

While investigating BUG 291850 I came across this issue. I've fixed BUG 291850
using a workaround (call KFileDialog::getExistingDirectoryUrl() instead which
opens the native directory selection dialog).
The problem is that KDirSelectDialog::selectDirectory causes an infinite loop
(see the attached patch for the reason).

Reproducible: Always

Steps to Reproduce:
Call KDirSelectDialog::selectDirectory() from an application.

Actual Results:  
Infinite loop plus a series of failed assertions.

Expected Results:  
Select a directory without problems.
