nspluginwrapper+openjdk6+linux-f10-flashplugin coredumps

[Peter Jeremy]

I have a rather strange situation on a FreeBSD 8-stable/amd84 box
where nspluginwrapper coredumps whilst processing
npwrapper.libflashplayer.so if it sees IcedTeaPlugin.so first:

server% nspluginwrapper -v -l                          
List plugins in /usr/local/lib/browser_plugins

server%

If I remove IcedTeaPlugin.so or fudge ~/.mozilla/plugins so
IcedTeaPlugin.so is after npwrapper.libflashplayer.so then it
all works as expected.  I've tried rebuilding each of openjdk6,
nspluginwrapper and linux-f10-flashplugin10 to no avail.  I've
tried ktracing nspluginwrapper and don't see anything obviously
wrong.  The coredump backtrace shows:
#0  0x000000000000f900 in ?? ()

#8  0x000000080050d5da in dlopen () from /libexec/ld-elf.so.1

Does anyone have any suggestions?
