Admin – widgets page failing to load

I just installed the latest nightly 3.2 Beta 1 using the Beta Tester plugin and it appears I’ve lost access to my Widgets page. Clicking the link in the nav results in a 404 every time. I event swapped themes to Twenty Eleven and tried disabling/re-enabling some plugins with no luck.

I’m hosted with Dreamhost (I know, I know) and I just ran the Health Check plugin to make sure I was good to go. I passed so my next stop was checking here with you guys.

Anyone run into this yet?
