There seems to be a serious bug with setting fonts in 0.7.4.
Possibly the font is destructed by the graphics object ...?

Well, I haven't used 0.7.4 for weeks, as I am working on the new
0.8.0 release. Setting fonts with this release should work
(it uses objects created on the stack, no pointers).

Unfortunately, this release is delayed until the end of the semester
(have to write several exams) which is ca. Mid July.

Perhaps you want to try one of the snapshots from
http://libufo.sourceforge.net/snapshots/
