Thanks Eliah. It was a somewhat rhetorical question, really. Help is borked.
I know jack about gio. However, whilst poking into this a tad I noticed the following: gio.app_info_get_default_for_uri_scheme() returns None for 'ghelp'. Related aside: as a check to see if I was using this method correctly, I tried to get the uri_scheme for 'http'. The following was returned: default for 'http' <gio.unix.DesktopAppInfo at 0x9c73cfc: Firefox 4.0 Beta 9 Web Browser> I wonder if this explains why, even though my session default browser is Chrome, Evolution insists on launching Firefox. But I digress.... gio does seem to know about yelp: <gio.unix.DesktopAppInfo at 0x9ae68ec: Help>, executable: yelp, supports_uris: False Odd that it doesn't support URIs.... Normally I don't change Summaries on other people's bugs, or downstream bugs. Pardon my making the exception in this case. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in ubuntu. https://bugs.launchpad.net/bugs/695260 Title: gnome-panel help cannot be displayed -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
