Description of problem:

I'm also seeing this kind of coredumps:

This looks like failure from accessing incorrectly converted pointer from 32bit
to 64bit platform - however I've no idea how it works internaly in the
nspluginwrapper.

I do not see these frequent Flash crashes when running 32bit mozilla with the
exactly same libflashplugin.so.
