Comment 18 for bug 176653

I am getting this error right now, but slightly different cause:

Setting up flashplugin-nonfree (9.0.115.0ubuntu3) ...
Installing from local file /var/cache/flashplugin-nonfree/install_flash_player_9_linux.tar.gz
Flash Plugin installed.
/usr/lib/nspluginwrapper/i386/linux/npviewer.bin: error while loading shared libraries: libselinux.so.1: cannot open shared object file: No such file or directory
nspluginwrapper: no appropriate viewer found for /usr/lib/flashplugin-nonfree/libflashplayer.so
dpkg: error processing flashplugin-nonfree (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 flashplugin-nonfree
E: Sub-process /usr/bin/dpkg returned an error code (1)

So it seems that this time it's a missing selinux 32bit library, rather than pcre.
