firefox/mozilla crash with linuxpluginwrapper on freebsd 4.11

[Philip Tellis]

Hi, I'm running the following:

FreeBSD 4.11
Firefox 1.0.7
Mozilla 1.7.12

I installed linuxpluginwrapper-20050910 and I'm trying to use it with flash6

I modified the /etc/libmap.conf file slightly because firefox was
looking for /home/usr.X11R6/lib/linux-flashplugin6/libflashplayer.so 
To fix this, I made the map match any file named libflashplayer.so
(since there is only one it does not matter).

My /etc/libmap.conf file looks like this:

# Flash6 (temporary setting)
[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 libstdc++.so.3
libm.so.6               libm.so.2
libc.so.6               pluginwrapper/flash6.so

(that is the entire file)

I noticed that libstdc++.so.3 does not exist on my system, but
libstdc++.so.2.95, so I changed the above line to that.  It did not
make a difference.

both firefox and mozilla segfault on startup.  For firefox, this is
the backtrace that I get:

Is this enough info to tell me what's wrong or do you need more info? 
I've searched the web for many weeks, and looked through the archives
of this list too.  I've tried everything that I could find online but
nothing solves my problem.

Thanks,

Philip
