It looks like this is a debug build, and so should have symbols.

Try putting "NSPR_LOG_MODULES=nsObjectFrame:4,Plugin:5,PluginNPP:5,PluginNPN:5"
and it may give some info on where Mozilla is up to.

The assertions are layout related and not necessarily related to the crash.

I'm not sure symbols are going to help here.  The stack looks corrupted.
