Hi
Yes, a comment would help.
Generally, if the bug has not already been confirmed it might help to add a new comment saying that you can reproduce the bug. Let them know the version of LO (4.2.0 alpha?) and the OS (eg Xp, Win7, Ubuntu 12.04, or whatever).
With the early stages of a new branch it is incredibly useful to add a comment in bug reports if a regression has occurred. The earlier the better as it might help the devs deal with it quickly while the code that caused it is still fresh.
