[XeTeX] problem with flashcards, polyglossia and RTL-languages

[Fabian Rieger]

Hi,

using flashcards class in combination with polyglossia and RTL languages 
I met a problem that wasn't there 6 months ago or so:
As soon as I add just a line of
   \setotherlanguage{arabic-or-farsi-or-hebrew-or-syriac}
(no arabic etc. text is required for this effect), the text on both 
sides jumps to the top of the resulting cards.

This happens with MiKTeX 2.8, updated today and MSWindows 2000;
in flashcards.cls the line
   \RequirePackage{geometry}
is replaced with
   \RequirePackage[paper=a4paper]{geometry}
and
   twosideshift=\oddevenshift,
is commented out.

A minimal example:

%\TeXXeTstate=1
\documentclass[avery5371,frame,grid]{flashcards}
\usepackage{polyglossia}
\usepackage{xltxtra}
\setmainlanguage{english}
\setotherlanguage{german}
\setotherlanguage{arabic}
\usepackage{fontspec,xunicode}
\begin{document}
\begin{flashcard}{texttexttext}
texttexttext
\end{flashcard}
\end{document}

Without "\setotherlanguage{arabic}" all text on the cards is centered as 
it was last year.

Is there any solution ?

Many thanks
