Just wanted to add that the problem seems to be related to an Inkscape property :

<marker
inkscape:stockid="Arrow2Lend" <--------- this is probably ignored
orient="auto"
refY="0.0"
refX="0.0"
id="Arrow2Lend"
style="overflow:visible;">
(...)

Just a note to say that I have redo a version of
http://commons.wikimedia.org/wiki/Image:Aikido_ikkyo.svg with manula arrows
head. So, in order to look at the problem, either use
http://commons.wikimedia.org/wiki/Image:Van_de_graaf_generator.svg or an older
version of ''Aikido_ikkyo.svg''.

I'm not sure it has anything to do with that property, it's more likely caused
by librsvg ignoring the "overflow:visible" style. Inkscape's default markers are
defined outside their bounding box and therefore rely on the overflow to be
visible in order to look correct. Librsvg, hovewer, ignores this overflow
attribute (http://bugzilla.gnome.org/show_bug.cgi?id=333118).

I guess this is a duplicate of http://bugzilla.wikimedia.org/show_bug.cgi?id=5163.

Don't know if this is the same bug:
http://en.wikipedia.org/wiki/Image:BJT_symbol_NPN.svg looks fine on the full-
size image page, but the thumbnail on http://en.wikipedia.org/w/index.php?
title=NPN&oldid=46322776 is missing the emitter arrow.

This image should have arrows and dots, neither of which appear.

On this image (http://commons.wikimedia.org/wiki/Image:Compression_JPEG.svg) I
have as a problem with arrow they are really small, in Firefox
or in Inkscape the arrows will be really bigger !!!

Is it the same bug, is there a work around ?

Upgrading to librsvg >= 2.18 would solve this.

Looks OK now that we have librsvg 2.22.0. The arrows in the first test case point the wrong way, but the rest of the test cases seem to be correct so I'll assume that the first one is an author issue.

Gilles moved this task from Untriaged to Done on the Multimedia board.
