Realplayer and firefox

[Steel City Phantom]

i just got realplayer installed and its recognized in firefox in the 
about:plugins screen.  but when i go to a site that loads the reaplayer, 
firefox core dumps and crashes.  these are the lines i have in my libmap 
and i have

#######################################################
# Helix RealPlayer with 
Mozilla/Firebird/Galeon/Epiphany/Konqueror/Kazehakase
[/usr/X11R6/lib/linux-mozilla/plugins/nphelix.so]
libstdc++.so.5                  libstdc++.so.5
libc.so.6                       pluginwrapper/realplayer.so


and in my run-mozilla.sh i added the path 
/usr/X11R6/lib/linux-mozilla/plugins to the moz_plugin_path tag.

ideas?
