Certain Help menu items (weblinks and IRC) do not work on OS X, or on Linux...

[Christian Herbig <c herbig me com>]

I am experiencing an issue where the Help menu items, “/menubar/Help/HelpWeb”, “/menubar/Help/HelpIRC”, and 
“/menubar/Help/HelpBug”, give an error message popup.  On Linux this can be solved by installing Midori (or 
other browser), however on OS X, it seems that it should activate whatever browser is installed there.  Is 
there a setting that needs to be passed to Gnumeric, or is there a setting in one of the .config directories 
or such to solve this problem?

Please advise.
