Yes, the container misses cairo. Could you try adding at, and see if
the problem persists?

How did I found it? (for myself and for future reference)

I identified that the problem is that the container misses something.
All work fine, if you don't specify the -C option.

Then the hard thing was to find out, what that something was.

I straced the thing in the container, and also did that with the working one,
outside the container.

The svg file was opened quite at the end, and I looked at the trace
from that point on.
It turned out that the image is tried to be opened as xpm... not as
png, as it should be.

Then I looked at the inkscape source, for quite a while...
The good thing to search for turned out to be Inkscape::Pixbuf, which
lead me to find that
inkscape uses cairo in concert with pixbuf.

Then I looked around the package definition of inkscape, where I found
no sign of cairo...

I tried adding it to the container, and it seems to be working fine here.
