Bug#870168: kate: Missing dependencies, file system browser plugin messageboxes error on activation and does not work

Package: kate
Version: 4:16.08.3-1
Severity: normal

Dear Maintainer,

I use kate but do not use KDE, my desktop is Mate. In Debian 9 if I try to turn on Kate's plugin "filesystem browser" error messagebox appears.
Plugin is nevertheless plugged into GUI but is empty and does not function. I searched through Inet and found this may be fixed by additional installation of packages:

% apt-get install kinit kio kio-extras kded5

This resolved the issue.
