5112 - I got a gtk menu related crash

Status: RESOLVED WORKSFORME

(Core Graveyard :: Viewer App, defect, P3)

Description

[Mo DeJong]

CVS build from Wed Apr 14 on a Solaris Sparc 5.6 box using egcs 1.1.1.

I was using viewer to look at this URL http://www.javaworld.com.
I opened a view source window and later closed it then I resized
the main window. At some point during this process I got this
core dump.

Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkObject'
Segmentation fault (core dumped)

This is inside the method gtk_menu_item_select_timeout()

gtk_menu_item_select_timeout (gpointer data)
{
  GtkMenuItem *menu_item;

  GDK_THREADS_ENTER ();

  menu_item = GTK_MENU_ITEM (data);
  menu_item->timer = 0;

  if (GTK_WIDGET_IS_SENSITIVE (menu_item->submenu))       (line 638)
    {


(gdb) print menu_item->submenu
$3 = (GtkWidget *) 0x0

So the problem seems to be that this menu item has no submenu.
I am not really sure if this is a mozilla bug or a gtk bug.

dejong: do you know what version of GTK you were using?

there was a fix commited in to GTK on April 9 that fixed some code in this area,
but I am not entirely sure that this would fix this.
