gtk+/gdk/gtk.c (gdk_event_wait) problem with multiapplets

Hi,

after some hours debugging the panel and some applets I found some
problem with gdk_event_wait.

There is some loop (near line 1724):

          list = inputs;
          while (list)
            {
              input = list->data;
              list = list->next;

              condition = 0;
              if (FD_ISSET (input->source, &readfds))
                condition |= GDK_INPUT_READ;
              if (FD_ISSET (input->source, &writefds))
                condition |= GDK_INPUT_WRITE;
              if (FD_ISSET (input->source, &exceptfds))
                condition |= GDK_INPUT_EXCEPTION;

              if (condition && input->function)
                (* input->function) (input->data, input->source,
                                     condition);
            }

The problem is that if you use multiapplets the element `list' is
pointing to at the moment of the `init->function' call is removed
within that function and you get a segfault in the next iteration
of that look.

Any ideas how we can fix this ?
