            Bug ID: 320319
           Summary: SFTP kioslave does not behave as expected with the
                    file opening dialog
    Classification: Unclassified
           Product: kde-windows
           Version: 4.10
          Platform: MS Windows
               URL: http://edony.tuxfamily.org/~xav/img/kde-windows-kate-s

                OS: MS Windows
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: network&files

This bug report is part of my experiments with KDE Development Platform 4.10.2
(latest stable from the GUI installer) using a 4 vCPUs VirtualBox VM running MS
Windows XP Pro version 2002 SP3.
These experiments mainly aim at trying Kate, Konqueror and the SFTP KIO/slave
under Windows so that working with Unix/Linux machines from a Windows
workstation stops being so painful.

Tested with Kate: entering sftp://user@hostname in the address bar of the File
opening dialog, then hitting Enter adds a trailing slash to the address,
prompts the KDE wallet password if needed then begins generating endless SSH
traffic to the target machine. A quick look at running processes shows one to
two kioslave.exe processes under klauncher.exe being endlessly renewed. The
madness stops as expected when clicking the "Cancel" button.

Reproducible: Sometimes

Steps to Reproduce:
1. Launch Kate
2. Click the "Open" button, wait for the dialog to pop up (might be long due to
the WMI backend issue)
3. Type sftp://your_username@some_remote_unix_machine in the address bar
Actual Results:  
* The file dialog may manage to list the remote files as expected, but the
inner part of the dialog will remain unusable.
* most of the time, the kioslave.exe processes are renewed endlessly
* the whole parent program may crash
* the file opening dialog may display a popup stating that the kioslave process
ended unexpectedly

Expected Results:  
The remote files should be listed and browsable without any slowdown or crash.

This cannot always be reproduced. Sometimes, it just displays a message stating
that the kioslave process has died unexpectedly. Sometimes, it is Kate that
crashes.
