Returning a menu item of 1 results in a crash (divide by zero)

[sanctiont]

Quick fix in layout menu items:

• (void) layoutMenuItems
  {
  [self.itemLocations removeAllObjects];

  CGSize itemSize = CGSizeMake(GHMenuItemSize, GHMenuItemSize);
  CGFloat itemRadius = sqrt(pow(itemSize.width, 2) + pow(itemSize.height, 2)) / 2;
  self.arcAngle = ((itemRadius * self.menuItems.count) / self.radius) * 1.5;

  NSUInteger count = self.menuItems.count;
  BOOL isFullCircle = (self.arcAngle == M_PI*2);
  NSUInteger divisor = (isFullCircle) ? count : count - 1;

  if (divisor == 0) divisor++; // bump divisor up to 1 if it is zero...
