Page Layout ⇒ fancyhdr(fancyplain) problem with two lined footer on 1st. p

[vivelafete]

Hi,
i have a little error in the fancyhdr package:

I would to show the following in my footer:

\fancyfoot[RO,LE]{\rightmark \\ \leftmark}
isn't working

in th first version i had:
\fancyfoot[RO,LE]{\fancyplain{}{\rightmark \\ \leftmark} }
worked fine

then I tried:
\fancyfoot[RO,LE]{sdfgds \\ \leftmark}
is working

first i had:
\fancyfoot[RO,LE]{ \\ \leftmark}
isn't working, but would look like I would.


first i had:
\fancyfoot[RO,LE]{ \leftmark}
is working but doesn't look like i would.


Does anybody know what I'm doing wrong or is this a fancyheader bug?

Thanks
