After doing an svn update to 25109 (and applying a small patch
to gtk/webbrowser.c to allow compilation to complete), I chased
down one source of the above "Gtk-CRITICAL" message.
In my case the call to get_container_get_children() in the first call
to
gtk/main_welcome.c's main_welcome_reset_recent_capture_files()
triggered the error message. This error seems to have appeared
because welcome_file_panel_vb was NULL at this time. The attached
patch simply tests for a non-null welcome_file_panel_vb before
attempting to get the child_list.
Is this the proper fix, or should welcome_file_panel_vb have actually
had a non-null value by the time
main_welcome_reset_recent_capture_files()
is first called?
Hope this helps.
Jim Y.
