Error messages from a plug-in

[Ernst Lippe]

What is the "official way" to display error messages from a plug-in to
the user?
Basically what I looked for was a simple window (perhaps even with some
threatening icon) that I could invoke with a single function call
(I guess that I have been spoilt by too much Delphi programming).
I could find no such thing in the standard Gtk/Gimp libraries.
