Can confirm... Did this also happen in previous versions?

krita 4.4.8 can also trigger this bug.

Imported the twitter icon .svg file

I can Import this with the 5.0.0 appimage on Debian 10 with no problem.
The attached screenshot shows the original opened file with a size of 7px by 15 px off in the top left corner.
The larger image is after I drag-scaled it up in size.

My file viewer shows the bird image as it should be.

I can also Open the file to get the attached 'Opened-Twitter-Bird.png' result with an image size of 24px by 24px.

This bug only appears under windows?

The bird .svg path opened as a path in GIMP

I forgot to test with Windows 10 :(

With the 5.0.0 appimage on Windows 10, the RAM usage increases rapidly with 'Very High' power usage and krita is unresponsive.

Krita appimage on Linux opens it and shows a malformed bird shape as seen in previous attachments.

Inkscape (on Linux and Windows) can open it with no apparent problems.

GIMP on (Linux and Windows) can open it as an image of the correct shape as a Layer content, i.e. raster image.
However, if GIMP opens it as a path then it is very strange, as seen by the path (in pink) in the attached screenshot - "GIMP-bird-path.png".
That path may have similarities with the shape presented by krita, depending how you look at it.

Inkscape seems to have a correct path as tested by marking the path and seeing the result.

The .svg file itself is unusual in various ways:

It is very 'bare bones' and has none of the metadata usually associated with vector applications.

It has a role = "img" statement which I believe is used for giving 'hints' to browsers.
I tried removing that but it made no difference.

The bird shape is a path but it has no style-line-fill-join-colour- etc information, it's a bare path.
Maybe it relies on standard default values for those.

I tried using that path to replace the bare path data of a 'well formed' .svg file and that then showed the same appearance in krita. 
So, it seems to be something about the path itself that krita does not get along with, especially on Windows.
Comment 7 Ahab Greybeard 2021-12-30 14:47:12 UTC
Correction for Comment 6:
It should say " With the 5.0.0 portable .zip on Windows 10", NOT "With the 5.0.0 appimage on Windows 10".

Bugfix: Properly handle flags in SVG path

We treated flags ("0" | "1") in elliptical path data as coords, which
isn't correct.
