index generation error

[Ganbold]

Hi,

I'm having trouble generating index on Handbook translation.
It seems the problem is related to the mail chapter, however I can't 
find the cause of the problem.

I have following problem:

daemon# make FORMATS="html html-split" GEN_INDEX=yes
===> mn_MN.UTF-8 (all)
===> mn_MN.UTF-8/books (all)
===> mn_MN.UTF-8/books/handbook (all)

And the problematic lines in generated index.sgml are:

<indexentry>
<primaryie>цахим захидал
</primaryie>
<seeie>захидал</seeie>
,
<ulink url="#MAIL-SYNOPSIS" role="AEN31975">Ерөнхий Агуулга</ulink> 
<secondaryie>хүлээн авах,
<ulink url="#MAIL-RECEIVE" role="AEN32111">Захидал хүлээн авах нь</ulink>
</secondaryie>
</indexentry>

I appreciate if somebody can give me some advices and recommendations.

thanks in advance,

Ganbold
