kio-extras-dbgsym 4:15.12.3-0ubuntu1 (amd64 binary) in ubuntu xenial

 A kioslave is a plugin designed to be intimately familiar with a certian
 protocol, so that a standardized interface can be used to get at data from
 any number of places. A few examples are the http and ftp kioslaves,
 which using nearly identical methods will retrieve data from an http or
 ftp server respectively.

 This package is part of the KDE base workspace module.
