Binary package hint: flashplugin-installer

Installing flashplugin-installer on a fresh amd64 Kubuntu install for beta 1 testing I got this error..

Setting up flashplugin-installer (10.2.153.1ubuntu1) ...
Installing from local file /var/cache/flashplugin-installer/adobe-flashplugin_10.2.153.1.orig.tar.gz
Flash Plugin installed.
nspluginwrapper: no appropriate viewer found for /usr/lib/flashplugin-installer/libflashplayer.so
dpkg: error processing flashplugin-installer (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 flashplugin-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)

Running the command from the postinst script I can recreate the error

$ NSPLUGIN_DIR=/var/lib/flashplugin-installer/ /usr/bin/nspluginwrapper -n -i /usr/lib/flashplugin-installer/libflashplayer.so
nspluginwrapper: no appropriate viewer found for /usr/lib/flashplugin-installer/libflashplayer.so

This causes a dpkg error during ubiquity install if the third party non-free box is ticked.
