Thanks for the report, that works correctly here, what do you get if execute: gnome-help ghelp:user-guide#goscustdesk-12 ? Could you also attach your ~/.xsession-errors file to the report? thanks in advance.

I've deleted .xsession-errors lately, and created a new one, but nothing is written into it. When running the command from the terminal, it opens successfully the Desktop customization document, and the following is output to the terminal:

(gnome-help:2403): Gtk-CRITICAL **: IA__gtk_tool_button_new: assertion `icon_widget == NULL || GTK_IS_MISC (icon_widget)' failed

A thing to note is that when running from the run application dialog, the document opened is not the Desktop customization document, but the Desktop User guide. (I don't know whether this is normal or not, but this means that running the same command from three different places results in three different things... I just don't understand why )

But as a workaround,
add MimeType=x-scheme-handler/ghelp;
to the end of your /usr/share/applications/yelp.desktop
I don't run ubuntu but this should possibly help you.

Terminal says "Error showing url: The specified location is not supported" when running the command "xdg-open ghelp:user-guide#goscustdesk-12"

Ok, try opening /usr/share/applicasions/yelp.desktop from a terminal as root (so su first or sudo)
and add
MimeType=x-scheme-handler/ghelp;
to the end of the file on a new line.
then
update-desktop-database -q
then
update-mime-database /usr/share/mime

Does that fix it?
