I've never hit these problems, though I have the source for everything I'm compiling in Rust in general.

I've run into it before, but it's not usually too serious. It only usually happens on lines with compound expressions or chained calls like this:

  foo.into_iter().map(|x| x+1)
     .filter(|y| y > 2)

My working theory is that it's related to situations where there's multiple statements on the same source line (or inside a block inside a lambda).

Yeah, quite possibly. I feel like I've stepped through some pretty gnarly iterator chains and it's worked surprisingly well. It is rare that I actually need to turn to the debugger, so I could be mistaken.
