This appears to a great extent a duplicate of
https://bugs.kde.org/show_bug.cgi?id=203724 but my KDE bugtracker account has
been trashed and I can't seem to be able to re-register. :( Perhaps someone can
forward to upstream if deemed appropriate?

One important detail: The offending KDE session is running on a Xephyr session
which is running on top of the actual X session.

Steps:

1. Start a KDE desktop session
2. Add a "Folder View" widget to the desktop
3. Change the target location to an SFTP or SMB URL (e.g,.
sftp://example.com/me, or smb://mymachine/Documents)

Expected:

The contents of the target URL would be displayed.

Actual:

No change to the view. The previous contents, if any, remain in place.

KDE version: 4.14.9
