Created attachment 113987 [details] test svg file When creating a text field in inkscape and put text with a newline there, that text will be displayed in one line in gwenview instead of the multiple lines. Test file is attached.
The same happens for the file preview. This looks like a QtSvg bug, or a non-supported feature in the Tiny SVG subset Qt supports. Please file a bug against Qt, thanks.
