Found that libpepflashplayer.so was missing from /usr/lib/pepperflashplugin-nonfree.
I downloaded the 64-bit Chrome deb from google, extracted libpepflashplayer.so, placed it in the proper location and pepperflash works now. Sorry, it appears this bug needs to be against pepperflashplugin-nonfree. Can someone please move the bug if they think it's appropriate? Thanks -
