A note: with KDE-4.1 you can also simply do

mime=`kmimetypefinder $1 | head -n 1`
kiconfinder `echo $mime | sed -e 's,/,-,g'`

Example:
mime=`kmimetypefinder freedesktop.org.xml | head -n 1`
kiconfinder `echo $mime | sed -e 's,/,-,g'`
--> /opt/kde4/share/icons/oxygen/48x48/mimetypes/application-xml.png

This has no support for <icon> and <generic-icon> though, but I think your script doesn't either :)
