Mozilla 1.7:error loading stylesheet:(null)

 error loading stylesheet:(null)

recently two days I deal with problem on solaris (sun)10 with mozilla 1.7 browser.
It always said error loading stylesheet:(null). I tried many method,then got the solution.
It is Mozilla support MIME type's problem. there is the package shared-mime-info which installs the file /usr/share/mime/packages/freedesktop.org.xml
Do step as below:
   1. cd  /usr/share/mime/packages
   2. vi  freedesktop.org.xml
  
     in this file there is comments like:
  <mime-type type="text/x-xslt">
    <comment>XSLT stylesheet</comment>
    <comment xml:lang="de">XSLT-Stylesheet</comment>
    <comment xml:lang="fi">XSLT-tyylitiedosto</comment>
    <comment xml:lang="no">XSLT-stilark</comment>
    <glob pattern="*.xslt"/>
    <glob pattern="*.xsl"/>
 </mime-type>
 just comment out that element
 <!--
 <mime-type type="text/x-xslt">
    <comment>XSLT stylesheet</comment>
    <comment xml:lang="de">XSLT-Stylesheet</comment>
    <comment xml:lang="fi">XSLT-tyylitiedosto</comment>
    <comment xml:lang="no">XSLT-stilark</comment>
    <glob pattern="*.xslt"/>
    <glob pattern="*.xsl"/>
  </mime-type>
  -->

   3.run command
   # dpkg-reconfigure shared-mime-info
   if you don't have this command
   run update-mime-database /usr/share/mime
