Perhaps it depends on environments.
On my lubunutu 16.04, concerning speed for all.dem at "make check", 
qt is faster than wxt.

(On windows, for all.dem execution, qt is rather faster than wxt. )

Back to the original issue, 

Gdk:ERROR:/build/gtk+2.0-KsZKkB/gtk+2.0-2.24.30/gdk/gdkregion-generic.c:337:miSetExtents:
assertion failed: (pExtents->y1 < pExtents->y2)

is not gnuplot specific after google search.

As you wrote in the first post

Perhaps this is an issue of some form of library version skew.
There seems to be difficulty in libraries of GTK+2, wxGTK and gnuplot.

If you have a chance to build gnuplot by yourself,
--with-wx-single-threaded 
at configure sometimes changes the situation.
(However, it may reduce the speed.)
