This is easily reproducible by starting (without mods) with a tribe (maybe others as well), then completely enclose the camp in walls and leave only one entrance.
Then create a huge maze of wooden traps in an S shape (100 traps in my test). Execute a mech raid of >1000 points (remove all but 2 centipedes).
These 2 centipedes will start their journey through the trap maze towards the camp and hitting trap after trap. Randomly you start seeing this message appear (sometimes even 20 times in a row)

if it matters, start was on merciless, randy random

I confirm this issue with build 1.0.2096 (without mods).
