SVG file upload doesn't work: "picture not available"

Hi there,

I uploaded an SVG (4.568 KB) to mural, but it's not displayed and shows the message "picture not available".

The resolution of the PNG and PDF versions of the file are not good enough.

Can anyone help me out and let me know what I can do to upload the SVG (I think it had worked in the past, but I tried it in many ways unsuccessfully now)?

Thank you!
