I have the exact same problem as the original poster. I am using Ubuntu 12.04 with nvidia proprietary binary drivers.

Logging in the second time is successful and I'm able to reach the desktop. It seems like these might be part of the same problem. I can't say for sure whether this is consistent behavior because I only upgraded yesterday. I'm using NVIDIA binary drivers with TwinView, Oneiric.
