Same stacktrace here, entirely vanilla:

Edit 2: reverse engineered it, seems to use boost's filesystem library to form a canonical path for the validation, dealing with ".." issues in a known good way. Maybe it's safe after all.
Yes, it is designed to be safe, but it needs to be rechecked for corner cases, like created shortcut files ...

It'll slip; Software projects (particularly games) always do. I'm boiling over with anticipation, too, but I've got a mop handy to clean up the mess.

Just right-click and hold on the item you want to repair (while within placement range, of course). That, or load them into your roboports and have your construction bots apply them

I noticed it in the trailer, and this is my one complaint: Copper bars just look dull when they're exactly the same as Iron. Please change them back, or to a new, unique model.

Trailer looks really, really slick. Great job! Love the bit where the bugs attack... and are promptly squished by trains

There's several recipes to make "Fuel Blocks" (one each for Light Oil, Heavy Oil, and Petroleum), which can be fed into boilers like coal, but provide more energy per item
