Cacti graphs displayed with squares after migration 1.4

Hello,

I was using rrdtool 1.2 and the ttf fonts in the past. Everything worked.
I recently upgraded my system to rrdtool 1.4 and from what I understood the font system changed.

What do you guys have in Console > Configuration > Settings > RRDTool Default Font ?
I have [NO FONT VERIFICATION POSSIBLE]

For the fonts I have
# fc-list | grep DejaVu
/usr/X11R6/lib/X11/fonts/TTF/DejaVuSans.ttf: DejaVu Sans:style=Book
/usr/X11R6/lib/X11/fonts/TTF/DejaVuSerif.ttf: DejaVu Serif:style=Book
/usr/X11R6/lib/X11/fonts/TTF/DejaVuSansMono.ttf: DejaVu Sans Mono:style=Book
And many others

Thanks
