yaws

Hello.

Who i cannot do following code?

{{ssi, "somefile", "%%", 
   [{"somewhat", yaws_api:ssi(Docroot, [Filename])}]}

Yaws 0.49 says:
=ERROR REPORT==== 8-Oct-2004::22:07:31 ===
Yaws process died: {function_clause,[{yaws_server,
                                         binary_size,
                                         [528,
                                          {html,
                                              [<<10,60,116,97,98,108,101,32,98,1
...
100,62,60,47,116,114,62,60,47,116,97,98,108,101,62>>]}]},
                                     {yaws_server,binary_size,2},
                                     {yaws_server,binary_size,2},
                                     {yaws_server,deliver_accumulated,5},
                                     {yaws_server,finish_up_dyn_file,2},
                                     {yaws_server,aloop,3},
                                     {yaws_server,acceptor0,2},
                                     {proc_lib,init_p,5}]}

It works if instead of yaws_api:ssi there is {ehtml, E}.
