Help text rendered as XML, stylesheet missing

[Steve Magoun]

Binary package hint: gnome-app-install

Launch "Add/Remove..." from the Applications menu. Click the help button at the bottom left of the window. The help viewer launches and complains,"This XML file does not appear to have any style information associated with it. The document tree is shown below." Instead of help text, I see a screenful of XML.

Possibly related: if you select a different section of the Add/Remove programs help (such as Introduction), you get a dialog that says, "Could not load section. The section ‘introduction’ does not exist in this document. If you were directed to this section from a Help button in an application, please report this to the maintainers of that application."

Help Viewer 2.18.1, Tribe 3 + all updates as of 02Jul07 3:30PM ET.

also see Bug #130024 and http://ubuntuforums.org/showthread.php?p=3137652

not sure if the bug is in the packages or in yelp.

[Ben (tuckergallitz)]

FWIW, I have the same problem, and starting yelp from a command line and doing the following gives some additional output.

STEPS:
start yelp from the command line
Click Adding and Removing Software
XML Garbage comes up

Command line output:
xmlXPathCompOpEval: function has-same-node not found
XPath error : Unregistered function
xmlXPathCompiledEval: 3 objects left on the stack.
runtime error: file /usr/share/xml/gnome/xslt/docbook/html/db2html-division.xsl line 317 element apply-templates
Failed to evaluate the 'select' expression.

I am also up to date on packages as of Aug 5th.

The same happened to me when going to "Info about Ubuntu" in the Gnome "System" menu entry.

We need to find the root cause/package for this.

Could you make a screenshot of the bug? Does it happen with yelp 2.19.1?

[sam tygier (samtygier)]

i can't take a screenshot due to bug #130822

but there is a screenshot at http://ubuntuforums.org/showthread.php?p=3137652

[sam tygier (samtygier)]

now that bug #130822 is fixed i have tested again. this seems to be fixed.

please reopen if you can still reproduce it.
