Public bug reported:

I've found this bug using the wnck python bindings (python-wnck)
package, but the actual problem is in the libwnck library.

I have python code where I have a list of X11 window IDs from an
independant source. I want to get a Wnck window from these Ids. In
poython, doing this:

window = wnck.window_get(my_xwindow_id)

does not work (window_get returns None) until i call
"wnck.screen_get_default()". This is because the window_hash table does
not get build until a screen is accessed.

libwnck./window.c lines 470-477 look like this:

WnckWindow*
wnck_window_get (gulong xwindow)
{
  if (window_hash == NULL)
    return NULL;
  else
    return g_hash_table_lookup (window_hash, &xwindow);
}

A possible fix would be to build the window_hash if it doesn't exist.
