Ok, so I have experienced my first real bug with Yosemite. I was letting someone use my laptop trying to convince them to upgrade to Yosemite when they clicked on iBooks and it popped up with this error:

They told me and I came over and clicked "Don't Reopen". Then I was greeted with the standard "iBooks quit unexpectedly." I reported it to Apple then tried again. Same thing. I opened up the Console and pulled up the crash. This is the top 1/8 of the crash. I can post the whole thing if needed, but I don't think it would be necessary and would probably be more characters then allowed by the forum.

I rebooted (as you can tell). I tried to Repair Permissions nothing came back for iBooks. Verified Disk, everything OK. SMC+PRAM reset didn't help (didn't think it would), and neither did a new user account. Booted in Safe Mode, same issue.
I'm thinking about doing a complete reinstall although I would prefer not to. I was told to do that by AppleCare but that is always their answer to everything.
It is worth nothing that I also updated to 10.10.1 B1 and the issue was still occurring. So this isn't just 10.10.1 but also 10.10. Is there anything, anything at all I can try before I reinstall OS X?
Any help would be greatly appreciated! Thank you.
