Infinite Loop when using SVG Image

on friday i wrote an email about an exception that appeart while i was
trying to use an svg image in FOP 0.25.. Now i have encountered another
Problem which i cannot really explain by myself. I attached an fo file
and a svg image used in the fo. When i try to render this fo as an PDF
Fop seems to be running into an infinite Loop.
The PDF which should be about 8 pages long is looped over 100000 pages
>_>. Killing the process after about 100k pages showed me a PDF File
which was about 300MB big and could not be opened in Adobe Acrobat
Reader.

Here is a slice of the output FOP generates...it rendered about 5
seconds...then i killed the process.

Do you have any ideas about what is wrong with that svg?

The SVG is probably too big to fit on the page. FOP creates a new page 
because it may fit on that page if there is less content or the page 
dimensions are bigger. However, in your case no pages are found which 
are big enough to contain the SVG. Try specifying an explicit size on 
fo:external-graphic or fo:instream-foreign-object tag.
