enable image scaling
The PNG file seems not to crash inkscape, but the issue is glyphtracer displays it a a huge resolution, which makes the glyph matching process unnecessary difficult (and rendering is much slower than it should).
My suggestion would be to enable image scaling in two modes: fit to image height and fit to image width. It would be perfect if these could be enabled with Ctrl+1 and Ctrl+2 keystrokes.
Thanks for your help,
