I took this topic to today's ESC (Engineering and Steering Committee) call and
the decision (according to suggestion) was to take some more time, keep an eye
and take a decision once 6.2 is getting closer to become "still" (i.e. the 6.3
release). From the minutes (to become available in the mailing list archives at
[1] sometime soon):

* keep kde5 as default on KDE Plasma and LXQt desktops for LibreOffice 6.2?
  (Michael W)
   + kde5 is currently default on Plasma & LXQt
   + tdf#124044 correctly states it’s not yet ready for “production”
   + concerned that by the time 6.2 is ‘still’ - will it be ready.
   + talked with Bubli – and suggest waiting some weeks until 6.2.5
   + happy if you are (Michael)
     + if you do the work – you decide (Miklos)
   => leave it to those doing the work to decide.

So basically, a decision is supposed to be taken in time for LO 6.2.5 (s.
schedule at [2]).

I do understand quite well. On the other hand, there's been quite some positive
reaction on kde5 as well, so I think it's reasonable to do as outlined above.

I'd like to encourage you to keep track of the current status and tell us how
you see it once again it get's closer to the 6.2.5 freeze.

In case you can still find out more about this, this would be really helpful
for any developer considering to look into this, and thus for getting those
ugly things fixed. It's OK for a bug to not be 100 % reproducible and say e.g.
"When I do this, about 1 out of 10 times, this and that fails." While those are
for sure not the nicest bugs to analyse, it's not uncommon and there are ways
to deal with that.

The packages provided by TDF actually don't include gtk3_kde5.

In case it's decided to "disable" kde5 for 6.2, the easiest thing would
probably be to revert commit [3], resulting in kde5 not to be chosen
automatically any more, but the order on KDE Plasma and LXQt then becoming:
gtk3_kde5, kde4, gtk3, gtk, gen
In your case, where gtk3_kde5 is not available, that would mean that kde4 would
be used (as desired).

People still wanting to use kde5 would then have to set the SAL_USE_VCLPLUGIN
environment variable (i.e. kde5 would become opt-in rather than opt-out in some
sense...)
