[Exim] file_expand not working in version 4.10?

hi,

i'm trying to migrate from sendmail to exim. i'm impressed by exim so
far. very flexible. i solved nearly all problems. the remaining one is
autoreply.

this is my transport:

# schickt vacation-msg
T_vacation:
   driver = autoreply
   file = ${home}/.vacation.msg
   file_expand
   log = ${home}/.vacation.log
   once = ${home}/.vacation.db
   once_repeat = 7d
   from = ${lookup{From} lsearch{${home}/.vacation.header} \
             {${value}} \
             {${local_part}@${domain}} }
   subject = ${lookup{Subject} lsearch{${home}/.vacation.header} \
                {${quote:${escape:${length_50:${value}}}}} \
                {${if def:h_Subject: \
                  {Re: ${quote:${escape:${length_50:$h_Subject:}}}
(autoreply)} \
                  {Bin ausser Haus} }} }
   to = ${sender_address}

works great, but variables in $file weren't expanded. so i assume
file_expand isn't working. or made i a mistake? i'm using 4.10 with
exiscan-patch.
