Sounds like error reporting is off for you setup, or environment != development?

I haven't dowloaded a fresh install for a while, I should do that.

Environment is development. reports are off.
How ever even in prod with no reports, empty white page is not very sweet, sounds as "blue screen of death" but it is white

In the normal case this should be 500 error (server misconfigured) in our case it's the System..

P.S. New instance comes without baseURL and in prod mode by default, so it is white screen for welcome...
