Unfortunately not able to replicate but when adding Google Analytics for WordPress as a plugin with my 15 other plugins, it caused an internal error and displayed a white screen for the dashboard.
I checked memory and apache error logs, nothing wrong there. Disabled the plugins and added back one by one and it was okay. I could activate Google Analytics for WordPress but could not connect with my Google profile. I had to deactivate the plugin - not sure it's 3.5 ready.
