 I don't think this is a bug. Its what tar does.
 
 A truss of tar when the directory exists, but has no files:
 
 mkdir(0x809b070,0x1ed)		ERR#17 'File exists'
 unlink(0x809b070)		ERR#1 'Operation not permitted'
 rmdir(0x809b070)		= 0 (0x0)
 mkdir(0x809b070,0x1ed)		= 0 (0x0)
 
 But when a file exists in the directory:
 
 mkdir(0x809b070,0x1ed)          ERR#17 'File exists'
 unlink(0x809b070)		ERR#1 'Operation not permitted'
 rmdir(0x809b070)		ERR#66 'Directory not empty'
 
 So it seems tar is removing then creating the directory if it is empty.
