Comment 2 for bug 511362

You have used 'Flowed text' which in its current implementation is not supported by other SVG viewers:

Inkscape FAQ: What about flowed text?

Inkscape manual:
<http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Text-Creating.html#Text-Enter-Flow>
Bug #167335 “flowed text (flowRoot) must be moved to inkscape namespace”:
<https://bugs.launchpad.net/inkscape/+bug/167335>

Easy rule if you want to create text objects that are fully compatible to other SVG renderers and the current SVG 1.1 specification:
«when creating text, CLICK, don't DRAG.
This way you get regular text that renders everywhere (but does not reflow).»
