What "I/O error occurred"? I mean the IntelliSense hint on the screenshot.

Looks to me like the description of `System.IO.IOException`, which is the possible exception.

I would guess the tool tips are slightly broken in that it doesn't list the exception class name or put it on a new line.

There you go, simple thing to contribute a fix for!

Good point, I might go ahead and make a patch.

That's what an IOException means. I suspect the hint text stems from a very minimal XML parse of the documentation.
