3) What is expected to happen is when one performs at the Terminal:
cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/689349/+attachment/1763870/+files/classnetwork.odg && unoconv --listener && unoconv -f pdf classnetwork.odg && acroread classnetwork.pdf

is it looks as it does in Evince.

4) What happens instead is acroread displays erroneous pixel-sized dots as per screenshot https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/689349/+attachment/1763844/+files/garbagescreenshot.png , while evince does not.

First reproduced in Maverick 1:3.3.1-1ubuntu3~maverick1, and reproduced in Natty, and Precise.

Unconfirmed OOo WORKAROUND: The upstream version does _not_ produce these effects and is fine.

To reproduce the problem just do the following:

1) Open any LibreOffice application (either Writer, Calc or Draw)
2) Create a figure (e.g. the smiley or an arrow)
3) Export the document as PDF
4) Open the created file

Results: Figures always have a black coloured 1x1 pixel at their top/left.

Doing some tests I found out the following:

1) The problem occurs on Adobe Reader only. The pdf reader on my Nokia works nice and other pdf readers seem to work (as the others reported), too.

2) It's always 1x1 pixel: In case I zoom in, things zoom as they should, but the single 1x1 pixel dot stays where it is and does not zoom.

Note: I used the attachment "PDF samle" for testing. The attached image shows the problem, just the way I see it, too.

It's not an Adobe Reader only problem. As I said I can view pixels in Foxit an PDF-XChange too. I don't use Adobe Reader, and I cannot test with it.

With Evince as PDF Viewer the dots are invisible. But the dots are still there, it seems. If you draw a smiley in Draw and convert it to curve, then ungroup the shape and go to Points mode, you can see the dots.

I confirm Clio's observations. That's something new and LibO specific OOo 3.1.1 and 3.4-dev do not show those extra points.

I think solving the extrapoint issue will also heal problems with PDF export.

Bug 31851 - Artifacts (vertical short lines) in PDF-Export indeed seems to be concerning the same problem like this one, please see my comments there when I mark it at a DUP of this one, because here we have collected much more information.

Unfortunately I do not know to whom we can assign this issue.

Did anybody find a workaround for this issue? I can confirm the bug for latest version of libreoffice in 11.04 from ppa (1:3.3.2-1ubuntu6~ppa1 ).
The same problem arises when creating an .eps figure, which is included into a latex document. This is due to latex converting the .eps to a .pdf file then containing the pixel-sized dots.

Rainer, I have not used any version of LibO for my last test and comment... I have simply tested attached test.pdf (pdf sample, fixed version) provided by Tor.

Ah, yes, please excuse me - my reasoning was too sophisticated.

Indeed, on your screenshot the dots can be found easily, and after I wiped the screen I now in a second attempt I also see them in Tor's PDF iwth AR X (but they really are nearby invisible).

So we definitely can NOT close this Bug.

@Tor:
did you also do clio's test after the fix? may be we had a double-bug, and only one has been eliminated with your fix?

Assuming question was directed at me - nope, don't think so, was just mislead by my debugger - my fix was indeed incomplete, working on an updated one.

In Ubuntu's LibreOffice, one can also reproduce this issue with KDE's Okular, and also by exporting to EPS first, and then using epstopdf to obtain a PDF file. So it seems to be something in the way LibreOffice generates the plot (EPS, PDF), that is not visible in EPS or some PDF viewers, but it is shown (or triggers a bug) in other PDF viewers.

Daily builds for master can be downloaded from https://dev-builds.libreoffice.org/daily/master/
After a patch is applied you need to wait two days until it is visible in these builds.
