Comment 3 for bug 726439

I am experiencing what I believe to be this bug on two Natty systems with yelp 3.0.0-0ubuntu2 (one amd64, one i386), but a bit differently than described in this bug report. Searching in yelp works generally, and I cannot produce the problem just by following the steps in the description. However, if I first do Go > All Documents, and then attempt to run my search (by typing it into the address bar and pressing enter), the search fails with "Unknown Error" "The URI ‘xref:search=nautilus’ could not be parsed. If I click the back button to return to the default page ("Ubuntu Desktop Guide"), I can again successfully search (though it doesn't search all documents, of course). On both machines, I am running yelp without arguments. The amd64 system is Lubuntu (set up by installing a command-line only system with the Alternate CD and then installing the package lubuntu-desktop on it), and the i386 system is Ubuntu running Unity.

@Dylan McCall
Are you able to reproduce this by following the steps in Jean-Baptiste Lallement's description precisely, or do you also have to do Go > All Documents (as you would likely do before attempting to search for a manpage) before attempting to search, in order to get the URI could not be parsed error message?
