Bugs in Gtk+/Glib-1.2.4

["Marting.Weber" <MARTING WEBER Allianz de>]

I ported the GIMP plugin gflare to Gtk 1.2.x. But when I call it I get some
error message. I think it is a Gtk problem and not a gflare problem. Please
tell me if it is my problem.
Here is the message I get when I start the gflare plugin:
Gtk_WARNING **: gtk_scrolled_window_add(): cannot add non scrollable widget use
gtk_scrolled_window_add_with_viewport() instead
GLib-CRITICAL **: file gmain.c: line 500 (g_source_remove): assertion 'tag > 0'
failed.
But the funtion gtk_scrolled_window_add() is never used by the plugin.
The second message appears when clicking on edit:
Gtk_WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with
width 65505 and height 65531
Gtk_WARNING **: gtk_widget_size_allocate(): attempt to allocate widget with

Please help to fix the bug. Here is the exact place where you can find the
gflare_ plugin for GIMP:
