IDEA 12 RC3 won't launch

Well, technically it launches. I get the "import previous version settings" dialog, then the license dialog, then the plugins dialog; then nothing, the main window doesn't come up. Anyone else seeing this?

IntelliJ IDEA 12.0, build IU-123.67 running on Mac OS X 10.7.4, Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)

This is on a fresh install. I've nuked ~/Library/[Application Support|Caches|Logs|Preferences]/IntelliJIDEA12 before installing this build.

Here's my idea.log:
