It appears that the extension_mappings hash is initialized to null, then
only instanciated if there is an AddType call in your conf file. Hence in
the type_checker phase it tries to perform a lookup on a null hash.
this patch should fix the crash, but IMHO by that point the
extension_mappings hash should just be empty, not null (i.e. it should be
initialized to apr_hash_make) --
