ok, i will try to submit a patch for Makefile.am, to see if they will implement on future releases (maybe is difficult, as they are forcing to use cmake and deprecating autotools, but who knows...)
if they don't , can you implement the patch in your built?

ps: in the meanwhile, they fixed the bug related to qt_qpainter: http://trac.navit-project.org/ticket/961

so i installed your latest packages for navit qt_qpainter and qml-gui, tried and it worked!

i modified two lines of navit.xml like this:
<graphics type="qt_qpainter"/>

<gui type="qml" enabled="yes" source="/opt/navit/share/navit/skins" icon_src="/opt/navit/share/navit/xpm/">

after a try, even if the qml gui looks like promising, more "shiny and futuristic", i still prefer the internal gui. the qml gui is still buggy, launch navit from xterm to see what happens.

especially the address search is not a good one
and i cannot change layouts

btw, using qt_qpainter should improve performance right?
maybe i noticed a little faster rendering for the map
so,if there is a better performance for the map rendering, i'll gonna use qt_qpainter with the internal gui
lets try you also and let me know your tests results
