I quickly tried C-x v g. This is what i found

1) No incremental blame support. That is we have to wait for the entire
history to be available.
2) ability to blame previous version/next version in the blame window
3) Ability to show the commit information on selecting the commit.
4) No scroll-all-window support so that boththe annotation information
and source code will scroll together

With respect to the bug. This bug happen only when semantic-mode is
enabled.
