Comment 2 Marcus Carlson 2010-08-31 18:44:40 UTC

From tasklist.c:

  window = gtk_widget_get_window (task->button);
  gtk_widget_get_allocation (task->button, &allocation);

  gdk_window_begin_paint_rect (window, &allocation);

  cr = gdk_cairo_create (window);
  gdk_cairo_rectangle (cr, &allocation);
  cairo_translate (cr, allocation.x, allocation.y);
  cairo_clip (cr);

Maybe we should check if window != NULL before continuing? Could it be that the window (button) is closed before glowing is done?
