Entire game environment is removed when a Kerbal tries to stand up after falling over

[ForgiLaGeord]

Windows version, running 32 bit version of KSP 0.25.0, used the launcher, but downloaded with Steam.

Curious as to whether or not a MK2 cockpit IVA had been added, I put just the cockpit on the VAB launchpad. Noting that there was still no IVA, I decided I would roll the cockpit over to the flag pole and climb up it. As the cockpit rolled past, I put the Kerbal (Fredfrod Kerman) out on EVA and let the pod keep rolling. He slid along the ground past the flag, and when he stopped and stood up, the screen went black, leaving only the HUD elements. Map view was also entirely black save for the HUD. Going back to the space center screen, it turned out that was also gone except for the HUD. I attempted to load a quicksave from before the event, but it was the same.
