Public bug reported:
Ubuntu 9.04, Intel Core 2 Quad
libglib2.0-0: 2.20.1-0ubuntu2
ibgtk2.0-0: 2.16.1-0ubuntu2
When using g_idle_add() in GTK+ apps the gtkFileChooser stops workning.
The following test code show the bug on my Ubuntu 9.04 system,
but the bug is not pressent under MinGW/WinXP.
The test app has a button that spawns a gtkFileChooser dialog.
if you uncomment the line g_idle_add(...) the dialog works,
otherwise it will be nonfunctioning

(window));

gtk_widget_show (button);
gtk_widget_show (window);
//Uncomment line below to remove bug
g_idle_add(handler,NULL);
gtk_main ();
return 0;
