CVS commit by howells: 

This is a partial fix for 76746. It at least stops the screensaver from crashing if a non existing 
directory is added.

the screensaver crashes on the QFileInfoListIterator it(*fileinfolist); line but unfortunately my Qt is 
compiled without debugging symbols and my poor iBook 800 really can't deal with recompiling the whole lot 
with debugging symbols again so I'm going to leave this bug open.

Also I'm not sure whether this should be considered a bug in KUrlRequester or not -- there is a 
KFile::LocalOnly mask, but this only stops local files being shown in the dialog, maybe KUrlRequester 
should have an isLocal() function or similar if a lan:// or something URL is entered.
