Bug#709255: browser-plugin-lightspark: Lightspark does not appear in Iceweasel's add-ons menu

[lex]

Package: browser-plugin-lightspark
Version: 0.7.2-2
Severity: normal

So, I tried to install the package "browser-plugin-lightspark" using apt-get,
then, opened Iceweasel expecting to fint it in the add-ons menu. It simply
wasn't there, as if I didn't install it. I checked in apt and both
lightspark-common and browser-plugin-lightspark were correctly installed.
