I got the following crash while trying to view the Entry for the Rune of Fire while trying to craft a Munchdew (Munchdew -> Rune of Gluttony -> Rune of Fire).
It is reproducible, it is not an insta-crash for me, it takes a tiny bit (1-2 secs maybe?).

Here's the full crash log: https://gist.github.com/SanAndreasP/04b46a78ce358dc6257a
And here's the stacktrace if you don't want to scroll through the massive file:
