managing SSRS 2012 service app in SharePoint 2010 returns 500 Internal Server Error

We're prototyping SSRS 2012 in integrated mode with SharePoint 2010 (single SharePoint server, single DB server). Setup seemed to complete successfully, including provisioning subscriptions and alerts, and setting content types on our report libraries. But... it doesn't work.  Opening Central Admin, then my SSRS 2012 application service, then clicking on System Settings throws a 500 Internal Server Error with a correlation ID. I put the trace log into Verbose mode for SharePoint Foundation and SSRS, but it doesn't offer much more information (see log below).

Any suggestions on how to go about diagnosing this?

Thanks in advance,

Quent
