This crash was worked around for FZ 0.8.98. I'm attaching the report here for future reference in case this is an issue anywhere else before (or with) the EBXL rewrite. Also, here is a link to neptunepink's reply in the MCF thread if this is useful:

Thank you for your time!

Duplicated with another mod (Veinminer). Testing the fix relative to that ticket.

Interesting. I'll patch this from our end shortly.
