I tried zwer's method, and got: "E: Couldn't find package libflashplayer". There is however a package called "adobe-flashplayer", but if you try to remove that one APT tries to install 110Mb worth of packages :S See this: http://pastebin.org/301058 for the output. The most important part is in the beginning and in the end.
rm /usr/lib/browser/plugins/libflashplayer.so
