If you're working on a RichTextBox control and get this error programatically:

System.NullReferenceException: Object reference not set to an instance of an object.

Congratulations, there's nothing you can do about it.  Microsoft has acknowledged that a random problem with this pops up in 2.0, and using Reflector shows that the code is the same.  They apparrently assume that some stream is not null and don't prepare to make sure that's correct.

Isn't 2.0 technically in beta state though?

Yes, but the bug also exists in 1.0 and 1.1.

So that's where that damn error comes from! I was getting this randomly a while back and it frustrated the hell out of me.

Yeah uh...  That's my comment down at the bottom.

Random, like radioactive decay random?

Isn't one of the features of radioactive decay that it is predictable?

No, you can only determine the probability of decay in a single atom.
