Steps to Reproduce

Include the steps I would need to follow to reproduce the bug.
So i was able to replicate this crash 5 times. Then i decided to try it with a different item. As soon as i did it with another item it no longer is crashing. So I am not sure how to get it to happen for you.

Back Trace (LUA Error Output)

You can get this through the use of !BugGrabber and BugSack addons.
Neither of the bug addons got anything because the game just crashed when i reloaded it showed no bugs present.

I've purchased a Lucy pet, and replicated the crash - it doesn't even require the AH to be open. Just trying to pick up the Lucy pet with the cursor triggers it (right-clicking doesn't)

However, this is not an Auctionator bug as it still happens when Auctionator is disabled, so this is not something I can fix.

You can still post the item, right-clicking the item when the AH is open will work to put it up for selling, or using the integrated bag view in the Selling tab will work too.
