This is still wrong from a usability POV. I may want to see the file/line for 
entry that have a name. And actually, there are afaik no situations where you 
could have a file/line but not a symbol name.

Again, why don't you align this with the other non-inlined frames, and honor 
the grouping setting? Check whether we group by address (then display file/
line), or by function (then display the function name).
