I assume you checked to see if the frame was broken or a bond line had failed?
You should be able to tell if a wide hub was used by the wear pattern in the face of the dropout.
I was thinking it might be something along those lines, but couldn't figure out why it would have been widened to 140 mm. Also it seems to be pretty straight, i'll measure it some time later tonight or tomorrow when I have time, but from the short ride I did have there was no noticeable pulls or anything.
As for the bonding, the ones on the bottom bracket appeared fine, I just checked them again and it kind of looks like a little bit of separation maybe on the brake bridge. Only on the bottom half and very small, fractions of a mm.
Thanks for the help.
