[Orgmode] Displayed math formula interrupts enumeration when exporting to html

[Longmin Wang]

Hi, 

I am using org-mode integrated in emacs 23.1.1.  When I export the org
file to html file, the enumerations will be interrupted by some
displayed math formulae. For example, the codes

  1. The first. 

  2. A displayed formula: \[ \int_0^{+\infty} \frac{c}{1+x^2}dx=1. \]

  3. The third. 

will generate

   1. The first.
   2. A displayed formula:
   <the formula>
   1. The third. 

Is it a bug? Or I made some mistakes in the source file.
