Screenshot don't have the .png extension
Submitted by led..@..il.com
I'm using GNOME Boxes 3.26.1 on Solus 3.
When i use "≡ -> take a screenshot", a screenshot is taken but is named for example "Capture d’écran depuis 2017-10-20 01-30-12" (it's french, "Screenshot from yyyy-mm-dd hh-mm-ss").
The image file is a totally valid png picture, but since there is not the .png extension, i have to manually rename each screenshot if i want to use a picture.
