I think Adrian is right; try to view the pdf file with Acrobat Reader
and not with Foxit.

The pdf generated from your sgv looks great here. (See the attached pdf.)

I do not know whether it matters, but I am using Linux and not MS Windows.

In addition, I would like to indicate that I did not select "convert
text to path" while converting from svg to pdf.

um, I just did this conversion using the May 8 version of Inkscape for
Win32, and I am not able to reproduce this problem, could you tell us which
version of Inkscape you are running, and which OS?

I use the Inkscape 0.46, built April 1 2008 on Windows XP SP2. Now I reinstalled it from http://inkscape.org, but it's still the same version. Where could you find the May 8 version?

I still have the same problem, and as I see, Paul also has it. If I look at the PDF Paul sent I can see the same coarse circles and letters in several pdf viewers.

here's the pdf file that I got : 
http://www.nabble.com/file/p17168440/Sokszog_APP.pdf Sokszog_APP.pdf 

the Inkscape came from : http://inkscape.modevia.com/win32/?M=D
in order to run this you'll need to use a 7-zip decruncher, can't remember
where that came from
but check out the pdf and see if it looks okay

You are right, I checked, and it’s the fault of Foxit Reader. Sorry for disturbing you about this problem.

I uncompressed and opened the PDF Paul sent in a text editor. The PDF 
contains both curves and lines. ie the curves had not been converted to 
lines. All the original information that is in the SVG file is in the 
PDF. This is a problem with the viewer problem.

The viewer will flatten the curves to lots of little lines when 
rendering. Normally the curves are flattened to lines of no more than 
one pixel in length so the flattening will not be visible on the 
display. In your screen shot it looks the curve flattening has been done 
once at the original size and the same lines have been used when zooming in.

The PDF displays fine in Adobe Reader and evince. I zoomed in on the 
circles in both viewers and there was no visible flattening.
