Because programmers get to a place where an error message needs to be displayed, write a six word message that might as well be an ancient Greek translation of Aramaic, and think to themselves, "I'll write a more useful message later". And later never comes. I say this with confidence, because I am one o' them critters.

I don't know what causes this message, but my first guess is that it's related to memory or some other system resource that runs short from time to time. I'd also guess that it's a fall back message, coming up when an event happens that does not, itself, have any error message at all. Which is what Karen said, so I'm being redundant. One of my charming qualities. :tt2:
