Dear ahneko,
Have you added your Google account, I think I know your problem. I've experienced same, not after flashing ROM, after factory reset.
Ok if your problem is that you can't add an account, do this try it:
First download root explorer by googling it.
Then on the top there will be a button like this Mount R/W click on that and then open System folder, in that open Etc folder, then you may find a file named hosts, long press on host and scorll down in the options, there you may find open in text editor*
There something will be written of 3 lines, erase that totally and paste this
(127.0.0.1 localhost
#127.185.66.4*android.clients.google.com)
After this go to settings accounts and try adding a Google account and if this method suceeds, I mean if you're able to successfully create a Google account, your problem is solved.
There is no risk in this method.
Please notify me if the method works
