gnomepager bug

[Roberto Zunino <zunino cli di unipi it>]

Since bugs.gnome.org seems to be down, I send this report to the list.

Using gnome-libs & gnome-core from CVS 27/3/99, gtk/glib 1.2.1:
- Open properties dialog
- Click on "TaskList" tab and gnomepager segfaults.

backtrace follows:

Program received signal SIGSEGV, Segmentation fault.

A random thought: note that I'm _not_ a gnome/gtk hacker and what follows
might be total nonsense!! I do not know how gdk works, too.

IMO: window=0x1e in gdk_window_get_type sounds a bad value. In
cb_filter_intercept event->any.window is checked for NULL, but of course
weird values != NULL. Moreover (*event) is a union and _perhaps_ 
event->any doesn't contain reliable info.

     default:
      if ((event->any.window) &&
          (gdk_window_get_type(event->any.window) == GDK_WINDOW_FOREIGN))
        return GDK_FILTER_REMOVE;
      else
        return GDK_FILTER_CONTINUE;
      break;

Hope this helps,
Zun.
