Misterious black rectangle on nautilus preview and transcoded pdf output

Reproduced with rsvg-view version 2.34.2 and 2.36.1 (nautilus uses librsvg to render SVG files).

> and also on the resulting PDF.

Not reproduced: a PDF file saved from within Inkscape (0.48.2, 0.48.3.1) does _not_ render the black square (truncated 'Flowed text' object).

> We have tried to isolate the element with no success: (…)

Please test the attached modified version of the file with the "offending" text object removed: the issue is a flowed text object which isn't visible in Inkscape (because the text completely overflows, and the content duplicates an existing text object beneath). [1]

Proposing to link as duplicate to bug #485269 (which makes it hard to detect the object which is causing the obscure balck rectangle.

[1] Note: Inkscape's 'Flowed text' is not supported by other SVG renderers. Please read the FAQ
<http://wiki.inkscape.org/wiki/index.php/FAQ#What_about_flowed_text.3F>
and the related note in the manual

Now it works great the modified SVG. I can see the problem. We had indeed a similar issue in another SVG and i've been able to correct it through plain XML editing in Gedit.

The generated PDF through Batik is also ok.

I couldn't really say if the inability to detect these kind of elements in Inkscape is a bug or a feature... you tell me.

Thank you!

Thank you for the feedback - glad you figured out a way how to address such issues with flowed text objects not visibly rendered in inkscape which appear as rectangles with a black (unset) fill in other SVG viewers.

Linking as duplicate to bug #485269 (it is not obvious how to detect and edit such invisible flowed text objects). Please add a comment and revert the duplicate status if you don't agree and think these are different issues.
