Bug#686942: cannot run yelp from serval gnome-applications

[Michael Stummvoll]

package: yelp,eog,epiphany-browser,evince,ghex,gparted,gucharmap,meld
Severity: important

Hi Maintainers,

I am not sure where it belongs and nobody could tell me, so I decided to send
this bug report against all packages in question. Hoping somebody with more 
expirence with gnome, yelp or whatever can reassign it to the right place

I cannot run yelp from serval gnome applications. I just get the error
message: "There was an error displaying help: Operation not supported".

There are no further informations provided to stdout or stderr, so I am
afraid I can't provide an more detailed error description.

I am using debian testing with yelp 3.4.2-1
I am not using a complete gnome environment, but have installed a few
gnome applications.

I tested the following applications where the error-message occours
- eog
- epiphany
- evince
- ghex
- gucharmap

also, when opening help from "meld" nothing happens.
only opening help from "gparted" works for me

besides that, opening an help-windows with yelp from console works:
> yelp /usr/share/gnome/help/evince/C/index.page

Kind Regards,
Michael
