Well I've converted an assortment of .flt files into .pfb using pfconv, using
the R15.4d loader (available at ftp://ftp.multigen.com/pub).

The problem, that I saw was related to pfLPointState conversion. perfly would
core dump as follows, whjile attempting to load the converted .pfb file:

   1 pfb_read_lpstate(0x104c3650, 0x1c, 0x104c3650, 0x1a)

   4 initSceneGraph(0x184ffec0, 0x0, 0x104c3650, 0x1a)

   5 InitScene(0x1865c580, 0x1c, 0x104c3650, 0x1a)

   6 main(0x2, 0x7fff2ed4, 0x104c3650, 0x1a)
["../../../../../sample/apps/C/common/main.c":125, 0x489f10]
   7 __istart() ["crt1tinit.s":13, 0x489c50]

The difference between R14.2 and R15.4 is that OpenFlight supports alot more
pfLPointState specification including calligraphic (in 2.2). It appears that
.pfb is having a bit of trouble with that.

Regards.
