Layout won't load on first login.

[Waverian]

As in, Blizzard frames aren't unregistered and my oUF frames don't exist. This only occurs on the very first world enter immediately following a fresh login. A UI reload fixes it. Logging out and then back in (to that character or any other) also fixes it. I've created dozens of layouts at various points in time and just starting experiencing this with my last two layouts, probably since about a week ago.

I have tried some debugging, mostly using a print call in the main body of the lua file as well as my layout function. On the first login, the layout function is never called. The global oUF object does exist at this time.

This occurs with oUF versions 1.3.28 and 1.3.26. I haven't tried others because of the sheer annoyance involved with tracking this bug down.

And that's about all I can think of that's relevant. The layout is relatively simple because of its infancy so I've included it following. Is this some error on my part and/or how can I go about solving this?
