Error in pagination when searching

I think I've found a little bug. Here are the steps to reproduce it:

• Go to "Repositories" and click on the last page of results.
• Make a search that yields less pages (I've tried "python")
• Bug! The search view tries to go to an inexsistent page because it includes the page number in the url.
• Also the error page comes with no style, probably due to a url issue.
