The Help manual browser could not find program documentation

[Istimsak]

The program "yelp" had to be manually installed after testing the gnumeric application. After installation, and pressing the "f1" button as instructed by the test manual, a help browser window did open but it could not find any documentation. The title of the window read, "Document not found", "The URI ‘ghelp:gnumeric’ does not point to a valid page". It looks like this help browser window acts like a search engine for program howto manuals. Unfortunately, it could not find any.

Does this still happen in Wily?

No, yelp displays the desktop guide

Same here, when pressing F1 in gnumeric I get: "Document Not Fount" "The URI ‘ghelp:gnumeric’ does not point to a valid page." Same Lubuntu release and package.
