A couple Tumbleweed packages are producing file conflict during installation.
The following message was observed after running 'zypper up' and the
installation process began:

File /usr/lib64/qt5/plugins/kded_desktopnotifier.so
  from install of
     plasma5-workspace-5.4.0-1.1.x86_64(repo-oss)
  conflicts with file from package
     kio-extras5-5.3.2-1.1.x86_64(@System)

File /usr/lib64/qt5/plugins/kf5/kio/desktop.so
  from install of
     plasma5-workspace-5.4.0-1.1.x86_64(repo-oss)
  conflicts with file from package
     kio-extras5-5.3.2-1.1.x86_64(@System)

File /usr/share/kio_desktop/directory.trash
  from install of
     plasma5-workspace-5.4.0-1.1.x86_64(repo-oss)
  conflicts with file from package
     kio-extras5-5.3.2-1.1.x86_64(@System)

File conflicts happen when two packages attempt to install files with the same
name but different contents. If you continue, conflicting files will be
replaced losing the previous content.
