It can't hurt to collect some errata in the spec..

vguArc Pseudocode (Page 147):

Code :
if arcType == VG_ARC_PIE
  MOVE_TO_ABS x, y
if arcType == VG_ARC_PIE || arcType == VG_ARC_CHORD
  CLOSE_PATH

Should be (LINE_TO instead of MOVE_TO)

Code :
if arcType == VG_ARC_PIE
  LINE_TO_ABS x, y
if arcType == VG_ARC_PIE || arcType == VG_ARC_CHORD
  CLOSE_PATH
