I tried your scenario with the following org file and I cannot reproduce
the problem:

--8<---------------cut here---------------start------------->8---

* some urls

  - [[http://www.google.com][google]]

  - [[http://www.google.com]]

--8<---------------cut here---------------end--------------->8---

The resulting LaTeX file (attached) compiles without error and produces
the expected output. 

HTH,
