As you can see from the following pictures, horizontal ruler in Writer is shorter from bottom than expected:
According to Jan Holesovsky (who redesigned the ruler bars) this is bug, but not related to his changes:
This might as well affect any other LibreOffice component, if you have a recent master built, please let us know, if it does or doesn't.
REPRODUCIBLE with LOdev version 3.6.0alpha0+ (Build ID: e3bc45b; installation file: master~2012-05-13_00.05.49_LibO-Dev_3.6.0alpha0_MacOS_x86_install_en-US.dmg), US English UI, on MacOS X German UI.
However, I'm not sure if the gap should be removed completely. If you try the same not with an empty document (like in the attached screenshots), but with a document containing much text, and scroll down half a page, the gap between the bottom of the ruler and the top of the first line of text visible seems useful to me. If the bottom line of the ruler would immediately touch the first visible line of text, some people (like me ;-) would consider this as irritating ...
So I think you should not just remove the gap, but discuss (with other UI experts) what would be the best visual solution: leave the gap, reduce the gap, or remove it, but introduce another separation between ruler and text (e.g., a semi-transparent transition, etc.).

The gap is useful (LOdev Writer 3.6 2012-05-13 on MacOS X 10.6.8)
The screenshot shows a situation in which the gap seems really useful to me; if you remove it, some other separation between horizontal ruler and text is necessary.
(Note that the rulers look grey / disabled; this seems to be a new bug (MacOS only?) which I have reported as bug 49914. But this is another issue, of course!)
Oh, sorry --
maybe I have misunderstood the report completely? I thought that "horizontal ruler in Writer is shorter from bottom than expected" was a description for the fact that there is a vertical gap between the bottom of the horizontal ruler and the page/text shown below it. But maybe you mean the *vertical* ruler and you are talking about the gap at the bottom of the *vertical* ruler?
If so, please forget my comments #1 and #2; they have nothing to do with your report. Sorry sorry sorry! I would like to delete them, but this is not possible. The word "horizontal" was completely misleading to me ...
However, I can also CONFIRM the gap at the bottom of the *vertical* ruler, if this is the issue you are talking about; this is indeed a bug and should get fixed. Please note that the screenshot I have attached is interesting for this question, too: it shows that the gap at the bottom of the *verical* ruler disappears as soon as the complete window is filled with text, e.g. when scrolling through a long Writer document. But when creating/opening a new, empty document or when the visible text does not reach to the bottom of the window, the gap is always visible. So REPRODCUBLE, indeed.

Roman, sorry for the misleading description. Of course I meant vertical ruler not horizontal. Also thanks for your input.

I tried with Impress and Draw -- the rulers seem OK for me, so at the moment this looks like a Writer-only issue to me.
Changed the Summary field by adding 'vertical' in order to prevent misunderstandings like my one (see comment #3 and comment 4), if possible ;-)
