Adding stevenjb@ also who is familiar with this kind of stack ( crbug.com/317489 ).

Thank you!
I don't know what to make of this crash. It looks like somehow MagnificationManager::Shutdown is getting called without MagnificationManager::Initialize, which doesn't appear to be logically possible without some other major problem.
