Bug#793740: kwrite: spell checking does not work at all

[Hagen Fuchs <code@hfuchs.net>]

Hey,

Alright, running kwrite with::

  LANGUAGE=en LANG=en kwrite

works (with spotty highlighting for auto-check, but yeah).
My locale says::

  LANG=en_GB.utf8
  LANGUAGE=en_GB:en

however.  I installed everything (on a clean slate Debian testing
machine) by saying::

  aptitude install kwrite sonnet-plugins aspell-en hunspell-en-gb \
    kde-cli-tools libqt5xcbqpa5

Note, I'm not running a KDE environment, hence the 'libqt5xcbqpa5'
package.  I'm simply using kwrite in XFCE (not even that's entirely
true, as I'm reporting this bug for somebody else :).

The kde-cli-tools report failure, too::

  $ kcmshell5 spellchecking
  Could not find module 'spellchecking'. See kcmshell5 --list for the full list of modules.

Nevertheless, I did a complete purge and reinstall cycle, even went so
far as to install 'plasma-framework' (I have no stomach to try
task-kde-desktop).  However, none of the above changed.

Hypothesis: hunspell is never asked.
Supporting: Removing aspell-en yields the same behaviour as before,
this time with

  No language dictionaries for the language: "en"

in the terminal.

Also:

Yes.  Yes, it does.  My point was, however, that a '/usr//usr/' path
anywhere can't be healthy.  But it can possibly safely be ignored, I
wouldn't know.

Thanks!
