Vino checks for the return of gtk_show_uri. If it's false, it displays an error
dialog saying there was a problem when opening the help.

I guess it would be good for gcalctool to both display a more explicative
dialog, and use gtk_show_uri instead of gnome-open. If I have time this weekend
I'll try to cook a patch.

Cheers
