Install themes > Search Results, Pagination is not working

When i search to install new theme, for example with “three-columns” tag i am getting 83 items as search results, displaying 30 per page, when i click on the next page to view the remaining, the search results are no more displayed. There after it is showing all the themes, in my case it is showing 1,121 items – showing 2 of 38. Please suggest me the right way of doing so.
