            Bug ID: 370440
           Summary: KML Export fails when destination directory partition
                    differs then the temp directory partition.
           Product: kipiplugins
           Version: 5.2.0
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: KMLExport
          Assignee: kde-imaging at kde.org
          Reporter: mettke at gmail.com

The temp directory in windows 7 and above is usually in the
C:\Users\[username]\AppData\Local\Temp directory.  When you try use a
'destination directory' that is located on a drive/partition that is different
then the C:\ drive (like the M:\ drive), the KML Export tools fails with the
following error:

"Cannot move data to destination directory"

It looks the failure is on line 538 of the kmlexport.cpp file.  The problem is
that the QDir rename function can't handle a rename across partitions (see
http://doc.qt.io/qt-4.8/qdir.html#rename).  The actual creation of the KML file
is successful, it is just not moved to the specified destination directory due
to this issue.  You will find the exported KML file and images in a the temp
directory, for example:

C:\Users\[username]\AppData\Local\Temp\kipi-kmlrexportplugin-8296

It took me awhile to figure out that the data was dumped to the temp directory.
 I actually had to look through the code to figure this out.  So I doubt a
non-programmer would be able to figure this out.

Reproducible: Always

Steps to Reproduce:
1. Select a image.
2. Select the Export > Export to KML... menu item.
3. Set the destination directory to something other then the C:\drive.
4. Click export.

Actual Results:  
The actual creation of the KML file is successful, it is just not moved to the
specified destination directory due to this issue.  You will find the exported
KML file and images in a the temp directory, for example:

C:\Users\[username]\AppData\Local\Temp\kipi-kmlrexportplugin-8296

Expected Results:  
The KML file and images are moved to the destination directory.

I'm not sure if this is an issue on Unix based system, it just happens to me on
a Windows 10 box.
