foo.desktop: Terminal=true no longer working with konsole5-16.08.x

[Rex Dieter]

Seems we've found a regression in recent konsole-16.08.x releases, that 
application desktop files with
Terminal=true
no longer work.

Issue is tracked
(downstream) https://bugzilla.redhat.com/show_bug.cgi?id=1376981
(upstream) https://bugs.kde.org/show_bug.cgi?id=368949

I'm investigating this, but any help or insight would be appreciated.
