I'm looking into it.
I believe there is a problem with the function that calculates the new Diff. It went from 0x251323ff to 0x2448a3ff
Before: 251323ff 0000001323FF0000000000000000000000000000000000000000000000000000000000000000000 0
After: 2448a3ff 0000000048A3FF00000000000000000000000000000000000000000000000000000000000000000 0
Heh, got it... (I think) Just waiting for retarget, or someone to shout fork... That would make sense of the +%400 diff and a fork occurred if someone was playing around and threw an asic at it, and maybe on the old wallet?

Gotta put in some discriminating code against wallet versions that are not the current when trying to debug.
