The CSS2.1 visual model spec says, in section 9.2.1.1:

"To make it easier to define the formatting, we assume that there is an anonymous block box around [inline content contained within a block that also contains block content]" [1]. 

We currently divide our lines into "block lines" and "inline lines". A "block line" has a single block frame within it. An "inline line" has inline content within it, possibly multiple inline frames. We should change our behavior to better match the spec, such that every line is a) a "block line", containing a single block frame which may or may not have inline frames. Since the spec specifically mentions that we should have an anonymous block to contain inlines within a line, we should change our behavior to match it.

How does this differ from bug 578901?

It doesn't. My initial search didn't find that.
