When I try to look at the help for a Gnome application, e.g. Brasero (I have the source for that so I can see what it is looking for), Help->Contents returns the specified location is not supported (similar with Gnome terminal & others). For Brasero I know it is looking for ghelp:brasero.
Checking the url-handler I get
gconftool-2 -a /desktop/gnome/url-handlers/ghelp
command = gnome-help "%s"
needs_terminal = false
enabled = true
Also gnome-help ghelp:brasero
(gnome-help:28544): Yelp-WARNING **: Failed to load config file: No such file or directory
OMF category 'GNOME|Accessories' not recognised, ignoring.
Then brings up the help page as expected.
My only conclusion is that XFce is not looking at the Gnome settings.
Is there something I have missed?
Sorry failed on my asking a question bit, system is CentOS 6.4.
