File:Ikaros solar sail key plain minusthosefivepaths.svg

English: Test upload of File:Ikaros solar sail key.svg saved as Plain SVG and then manually edited to determine whether https://bugzilla.wikimedia.org/show_bug.cgi?id=17845 is related to this problem.

1. This time I did not remove the "-inkscape-font-specification:DejaVu Sans" from each text element

2. I only removed the five path elements from File:Ikaros solar sail key plain.svg

Notes from File:Ikaros_solar_sail_key_plain_edited.svg copied below:

After I removed 5 path elements from revision 20:40, 12 June 2010 to upload revision 20:42, 12 June 2010, Wikimedia now renders the text correctly.

The SVG code just before the 5 path elements is:

  <text
      x="162.47852"
      y="138.45995"
      id="text3304-3"
      xml:space="preserve"
      style="font-size:32px;font-style:normal;font-variant:normal;font-weight:normal;font-stretch:normal;text-align:start;line-height:100%;writing-mode:lr-tb;text-anchor:start;fill:#000000;fill-opacity:1;stroke:none;font-family:DejaVu Sans;"><tspan
        x="162.47852"
        y="138.45995"
        id="tspan3617">Tethers</tspan></text>

This is the SVG code removed:

This is the SVG code after the removed paths:

   <text
      x="159.24414"
      y="179.82025"
      id="text3304-3-6"

      style="font-size:32px;font-style:normal;font-variant:normal;font-weight:normal;font-stretch:normal;text-align:start;line-height:100%;writing-mode:lr-tb;text-anchor:start;fill:#000000;fill-opacity:1;stroke:none;font-family:DejaVu Sans;"><tspan
        x="159.24414"
        y="179.82025"
        id="tspan3684">Main body</tspan></text>

Numbered key to File:Ikarus solar sail open.svg, a diagram of Ikaros solar sail when unfurled, facing the sun. Expanded key:

1 (blue square on a line) Tip mass 0.5 kg, 1 of 4
2 (orange rectangle) Liquid crystal device, 1 of 80
3 (blue square) Membrane 7.5 um thick, 20 metres diameter
4 (black rectangle) Solar cells 25 um thick, 1 of many
5 (yellow and blue lines) Tethers
6 (blue disc) Main body
7 (yellow dots) Instruments

Any rendering problems are probably due to wikimedia software. See key with alternative font in File:Ikaros solar sail key liberation sans.svg; the Opera browser renders all these SVG files fine.
