...that stack trace was bogus. here's the real one:

.... etc. basically bezier_add_lines() calls itself until something chokes,
which seems to happen because of bogus points passed in:

878 bezier_add_curve(ddisp, curve, &bezier);
(gdb) print points
$1 = (BezPoint *) 0x8198df8
(gdb) print points[0]
$2 = {type = BEZ_MOVE_TO, p1 = {x = -NaN(0x8000000000000),
y = -NaN(0x8000000000000)}, p2 = {x = 6.2864363363984459e-312,
y = -NaN(0xfffff00000020)}, p3 = {x = -NaN(0xfffffffffffff),
y = -NaN(0xfffffffffffff)}}
no clue yet why this is happening....
b.c.
