The GVText function from the vfonts module, cf. vfonts_Init. Looks
like R_FindSymbol is malfunctioning. You might be able to catch the
problem by tracing into R_FindSymbol from vfonts_Init with gdb.

(Not that I'm open for helping you out with gdb the next couple of
weeks. This is just an evasion from the stuff I *ought* to be
doing...)
