Yes, you will only see this error message on startup, and it is indeed
then only for GTK2 version of evince lib.

hmm, not sure what you are seeing here. If you click the Score button in
the print preview window it should typeset the whole score and display
it in the print preview window. The Refresh button in that same button
bar should repeat the last typeset command (score, movement part or even
ones from the print menu if they are set up to do this, e.g. print with
ambitus).

no

The button on the toolbar that has the print preview icon should display
the print preview window and run the typesetting the score command. At
the moment it is just showing the window, you have to click refresh
yourself - I will fix this. The same is true for the menu item
File->Print->Print Preview
Note that this menu item (if you right click it) is the command
PrintView, and not the old command PrintPreview, which still exists and
still does what it used to do, namely launch the external viewer. This
is to avoid breaking existing scripts.
If you are getting the external viewer launched for this then you likely
have your own version of the commands/shortcuts/denemoui.xml files
(Or I do :)
To check, look at the name of the command (right click, or hover for
tooltip).
