Bug Description

Binary package hint: rhythmbox

Crashed when trying to use ubuntuone-music-store plugin - as am in Australia I get the world store, and I simply clicked on the first item listed in 'World Store Top Picks' on the front page (Oasis - Definitely Maybe) and rhythmbox crashed. I can reliably reproduce this by clicking any item on the front page.

As can be seen from the stacktrace this looks like a crash in the flash player, and after uninstalling adobe flash player I can no longer reproduce this crash. Will try later with gnash or swfdec perhaps... this is a shame as in general the adobe flash plugin is perfectly stable in Chrome / Firefox

Why low importance? This crash makes the music store completely useless when adobe-flash-plugin is installed as it consistently crashes...

As a note - this is actually an assert failure in nspluginwrapper, rather than flashplayer itself - which is needed for the 32-bit flash player on 64-bit ubuntu - as a result it can be worked around by manually installing the native 64-bit adobe flash plugin from http://labs.adobe.com/downloads/flashplayer10_64bit.html (simply copy libflashplayer.so to $HOME/.mozilla/plugins - you may need to create the directory).

the issue is not really a muscistore one though, rather one in the wrapper code
