core dump

[caleb]

Hi, I am using 5.4 STABLE and am getting a core dump when I use the 
Helix Real Player 10 plugin for Firefox 1.0.4. The output from my 
/etc/libmap.conf is as follows;

# Flash with Firefox
[/usr/local/lib/linux-flashplugin6/libflashplayer.so]
libpthread.so.0 pluginwrapper/flash6.so
libdl.so.2 pluginwrapper/flash6.so
libz.so.1 libz.so.2
libstdc++-libc6.2-2.so.3 liblstdc++.so.4
libm.so.6 libm.so
libc.so.6 pluginwrapper/flash6.so

# Acrobat 7.0  with Firefox
[/usr/compat/linux/usr/local/Adobe/Acrobat7.0/Browser/intellinux/nppdf.so]
libc.so.6              pluginwrapper/acrobat.so

# Helix Realplayer with Firefox
[/usr/local/lib/linux-mozilla/plugins/nphelix.so]
libstdc++.so.5                  libstdc++.so.4
libc.so.6                       pluginwrapper/realplayer.so

I used the examples in 
/usr/local/share/examples/linuxpluginwrapper/libmap.conf-FreeBSD5-stable
as a guide for setting up the plugin. I checked /var/log/messages and 
found the following entry in reference to the core dump;

Jul  9 21:15:15 localhost kernel: pid 674 (firefox-bin), uid 1001: 
exited on signal 6 (core dumped)


Below is the last few lines of output after I use firefox to access a 
page which requires the plugin;

Break: at file nsPresShell.cpp, line 3592

Any insight would be appreciated,
