Why are you inheriting from SystemErrorView? AFAIK, doing that will only
gain you the ISystemErrorView interface which causes the publication to
log the exception as a "SiteError".

Apart from the 'index.html' bit which is annoying but not dramatic, what
is it that you'd like to fix?
Note that we Grok could actually set the default view for all Exceptions
to 'index' as well. That would make the 'index.html' pain go away. Of
course doing this would break everybody's custom exception views because
right now they'd be registered as 'index.html'.
