While debugging some issues with SVG converters, I'm a bit confused
now. I had configured an SVG -> PNG conversion rule in my

images when editing in LyX. Sadly, it seems that LyX is not applying
the rule anymore. Here's the message log info:

I just checked with LyX 2.2.3 on Linux Mint, and the same thing
happens to me (minus the part about Inkscape, which I do not have
installed). LyX claims to have the ability to display SVG files
directly, says it's doing a non-conversion (from == to) and then can't
convert the file.
I'd be inclined to suspect a missing library, but I have libqt4-svg
and libqt4-svg:i386 installed, along with a half-dozen other SVG
libraries. That said, GIMP shows my test file as a blank canvas, and
the default image viewer will not load it.
Okay, I partially retract what I said. I don't have a lot of SVG files
lying around, and the first ones I tested (all from the same source)
generated exactly the same error messages Cris reported.
Just now, though, I tried a few others I tracked down on my drive,
including some .svgz files provided by LyX (in /usr/share/lyx/images on
Linux systems) and the only .svg file I could find from LyX
(/usr/share/lyx/doc/clipart/SVG-Drawing.svg). They all worked fine, as
did a non-LyX SVG file I found in one of my folders.
So apparently there's something "off" about the SVG files that caused
LyX to spit up the error messages, and maybe there is similarly
something different about Cris's images.
