Thanks. First time my SpectMorph plugin just works as it should with upstream
suil. :-) There is one slight problem remaining, if you try to use a Qt4 and a
Qt5 plugin UI in Ardour5, this message pops up:

(ardour-5.8.165:3744): GLib-GObject-WARNING **: cannot register existing type 'SuilQtWrapper'

(ardour-5.8.165:3744): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed

This is because the class names defined by the wrappers are identical. Simple
renaming of the Qt5 wrapper class will solve this:

Sounds ok to me.
