That is very good to know.  I will follow that advice.

Thanks again for the quick response,

<opinion ignore="as you like">

Not a dbus issue per se I know:

The larger picture as it seems to me, is that published standards (such as 
org.freedesktop.StatusNotifierItem, in my case) should also specify a set of 
error names to be used by those implementing the standards.  Absent that, 
having an error name in an error message doesn't seem have any value beyond 
that of the free form error string also allowed in an error message.
