    - Did the callback in question have time to run before
      your expose event ?

    - Did you check the return value of
      gtk_file_selection_get_filename () ?

    - Did you really shadow the global "filename" variable with
      the one in your callback like so:
      > gchar filename = gtk_file_selection_get_filename(GtkFile ...

    - Did you do something like this:
          gchar  smash_string[16];
          gchar *filename = "default";
          memset (smash_string, 0x0, 20); // <-- Nullify filename
      hehe, thats far fetched but its happened before ;-D

Cheers,
