It's in a bunch of threads as the answer, and I didn't know at first, so I thought I'd throw it out as general advice:
Try Disabling your add-ins if you're having issues loading or crashing. Then turn them back on one at a time. And look for updated versions.
I've been having all kinds of problems, and this fixed them.
Master Merchant still has issues, so I just turn it on when I'm at the bank or at Guild Merchants & then turn it back off.
