  <p>An exception to this rule is when White has "wasted" a lot of moves on the king side, usually through a pawn "storm" <em>before</em> you castled. This would have given you time to get a center counterattack going. Then, castling long puts a rook on the d file which may be the coup de grace to White's center. More to the point, you will be able to "snipe" at White's exposed kingside pawns, and ultimately his king (which will probably be there, or in the center), without danger to your own king. </p>

  Black castling long in the Sicilian is a rare thing indeed. I can think of a few reasons:
  
  Black castling long is very rare in chess in general, only a few slow going openings (Caro-Kann, Scandinavian) feature it in general. It takes longer to prepare for long castling than for short castling, the king is less safe on c8 than on g8, white moves first so it's even riskier for black than for white.
  In the Sicilian, white generally gets quick development and an attack so it should be even more dangerous.
  Black has moved 1...c5, making the queenside less fit as a home for a king. 
  Besides, one of the ideas of the Sicilian is to play along that c-file with a rook on c8, doesn't combine well with castling long.
  
  So in general black only goes queenside if white has a full-force attack on the kingside and the center, and there is basically nowhere else to go.
  I can think of one exception right now in the c3-Sicilian, where the queens are off the board and black can castle with check: 
  [FEN ""]
  
  1.e4 c5 2.c3 d5 3.exd5 Qxd5 4.d4 Nc6 5.Nf3 Bg4
  6.Na3 e5!? 7.dxe5 Qxd1+ 8.Kxd1 O-O-O+ *
  
  and lines similar to that.

  Normally, you don't want to castle "long" in the Sicilian because of the missing c pawn, which can make the king very vulnerable to attack.
  
  An exception to this rule is when White has "wasted" a lot of moves on the king side, usually through a pawn "storm" *before* you castled. This would have given you time to get a center counterattack going. Then, castling long puts a rook on the d file which may be the coup de grace to White's center. More to the point, you will be able to "snipe" at White's exposed kingside pawns, and ultimately his king (which will probably be there, or in the center), without danger to your own king.
