UE 1 supports automatic occlusion and it is that feature that causes this error. It also only happens in UnrealEd to my knowledge but even so, when it doesn't even run in UED don't expect the game to work either...
Here's what happens: While moving around your 3d viewport suddenly becomes completely empty and black and the only things still visible are the purple mover brushes. You cannot move anymore and you have to ctrl-alt-del UED or crash out with a General Protection Error. Even worse, after reopening the level the same might happen again within a few minutes or you might not be able to open your level anymore at all.
I am not 100 percent certain about the cause but it is likely a brush somewhere that goes completely wrong and thereby completely screws up the occlusion calculations resulting in having the engine not render anything anymore and crash. That brush is still there after you reopen the map so for obviously it's bound to happen again. However, this also seems happen if you have a slow PC and a too complex level.
In general if it only happens once, do not care about it. Else fix it by doing this - First of all open your level but make sure all viewports are set to a 2D view before opening the file. Then try to see if you can find the brush that causes the problem. Complex brushes, or stuff that just looks wrong, non convex etc. might all the the cause. Also try to rebuild again + try not to run the optimization process. If that still doesn't fix it, and it likely won't actually, you will need to export-import the level from a t3d format .
