nspluginwrapper, npviewer & iceape

["Thomas H. George" <lists@tomgeorge.info>]

My system is messed up and iceape locks up trying to display some
images with the error message

sh: /usr/lib/nspluginwrapper/i386/linux/npviewer: not found

In fact there is no directory nspluginwrapper in /usr/lib.  The command
dpkg -l nsp* responds

Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

ii  nspluginwrapper-i386                 1.0.0-2                           A viewer for i386 compiled Netscape 4 plugin

and locate nspluginwrapper responds

/var/cache/apt/archives/nspluginwrapper_0.9.91.5-2_amd64.deb
/var/cache/apt/archives/nspluginwrapper_1.3.0-1_amd64.deb
/var/lib/dpkg/info/nspluginwrapper-i386.list
/var/lib/dpkg/info/nspluginwrapper-i386.md5sums

but locate npviewer finds nothing.  Something has gotten clobbered.  My
system is Squeeze running on a 2.6.32-5-amd64 kernel image.  Do I still
need an i386 wrapper?  If so how do I restore npviewer?  I tried
following the instructions in iceape/help/about
plugins/plugindoc.mozdev.org and got as far as entering the command

nspluginwrapper -i
/usr/lib/browser-plugins/npjn2_linux_jasper_pthread.so

which fails with message 

bash: nspluginwrapper: command not found

Can someone point me in the right direction?
