Summary0002836: Line breaks in SVG not rendered
DescriptionUsing a simple SVG file with just a text in two lines (containing line break) kdenlive shows only one line.
Steps To Reproduce- Produce in inkscape a SVG file with a text on two lines (or download the attached sample)
- Add to a new standard project
- Look at the render monitor: the text is only on one line.
- Same file on Rekonq or firefox or Opera or LibreOffice or Inkscape is shown fine.
  (KDE preview is also broken indeed)
Additional InformationKDE 4.9.3

This is a regression, for sure I've used these files with KDE 4.8.x

It could be due to KDE libs issue, but I couldn't investigate further, sorry.
TagsNo tags attached.

svg file can be displayed using the pixbuf or qimage producer. There seems to be a longstanding issue in Qt with svg line breaks:
https://bugreports.qt-project.org/browse/QTBUG-8137 [^]

Can you try loading your svg file with pixbuf and qimage (if you have both producers installed) to check which one fails?
In a terminal:

melt qimage:myimage.svg

melt pixbuf:myimage.svg

A could not execute your commands:
-qimage -> segmentation fault
-pixbuf -> failed to load "pixbuf:test.svg"

Anyway:
- dolphin preview is corrupted
- gwenview render is corrupted.

It's strange since gwenview bug seems to be solved "mainstream". :\

Ok, interesting. I discovered a problem in MLT's qimage producer that causes a crash when using it from a terminal, so it also probably crashes on rendering. Patch sent for review on MLT's github.

The source of the bug is definitely in Qt. The bug was marked fixed in KDE's bugtracker since it's a Qt issue. However the issue was NOT fixed in Qt.
