[Bug 856534] [NEW] flashplugin-downloader installs wrong alternative if nspluginwrapper not yet unpacked

[Steve Langasek]

Public bug reported:

The flashplugin-downloader has the following code in its postinst:

                if test ! -x /usr/bin/nspluginwrapper; then
                        for p in $VARIANTS; do 
                                update-alternatives --quiet --install "/usr/lib/
$p/plugins/flashplugin-alternative.so" "$p-flashplugin" /usr/lib/flashplugin-installer/libflashplayer.so 50
[...]
                        done
                else
                        NSPLUGIN_DIR=/var/lib/flashplugin-installer/ /usr/bin/nspluginwrapper -n -i /usr/lib/flashplugin-installer/libflashplayer.so
[...]
                fi

When installing on amd64, we must *unconditionally* use nspluginwrapper
because the 32-bit plugin cannot be loaded directly by the browser, but
the dependency on nspluginwrapper comes from flashplugin-installer - so
nspluginwrapper is not guaranteed to be unpacked yet when flashplugin-
downloader's postinst runs, with the result that sometimes the flash
plugin will fail to be registered correctly on an amd64 install.

I don't know if we want to still keep the flashplugin-downloader
nspluginwrapper handling, to prefer use of nspluginwrapper if it's
available even on i386 systems; but we definitely need to add a postinst
to flashplugin-installer for amd64, to ensure we handle the amd64 case
robustly.
