where do you get filename_to_add from? if you e.g. retrive the current value
from an GtkEntry which will not duplicate the string contents for you, you
need to copy the string so it doesn't get messed up by other things working
on your data. i.e. try:
gtk_clist_set_row_data_full ((GtkCList*) p_list,
                             number,
                             g_strdup (filename_to_add),
                             g_free);
