Well, just wanted to confirm that I am having the same issue with the Auto Exposure button as well. I have been using Aperture since version 2. Same situation that you are facing as well. Always have to Force Quit to gain access to the library. I will try to see if the minor adjustment makes a difference with the Auto Exposure button. If I find anything worth posting I will update this thread.

I have gone ahead and done what I wanted to do.
1) Deleted the old Aperture library (140 GB)
2) Restored from the brand new Vault (35 GB)
3) Selected all images and chose Photos - Generate Thumbnails
The thumbnail creation took some 30 hours...
But now that it's complete, it seems to have been worth it:
The size of library has virtually halved: from 140 GB to 73 GB (Thumbnails are now 36.5 GB, previously 84 GB, all "odd" folders have disappeared).
Also, it appears as if the previous crash problems may have disappeared (note that this is early days). But freeing up 70 GB on my SSD is pretty good in any case!
Perhaps Aperture 3.4.3 (or one of the other recent versions) has become better at creating vaults without copying any corruption in the source library?
My suggestion: if you have similar problems, try creating a brand-new Vault and see if this is much smaller than the original library (or older Vaults)...
