Comment 16 for bug 610820

I see three different bugs discussed here:
1. The issue with all packages shown as 1K size (comments #1 - #4), apparently solved
2. The issue that the total size is shown different from the size of the single packages (#0 plus #5 - #9). That one is already discussed in bug 410310
3. The issue that all packages are shown with 704M size (#10 - #14)

Which one should now be discussed here?
As the most recent discussions are about the 704M issue, and the other two are either resolved or covered elsewhere, most probably it's the 704M issue?
