The problematic SVG

SUMMARY
The only information that is preserved from the import is the outline. There is no color, and fill/stroke failed to fix the issue.

STEPS TO REPRODUCE
1. Simply import this file into Krita or open it.
2. Type in a number. 96 or 300 would be fine.

OBSERVED RESULT
See nothing. But, at least there is a vector layer with outline.

EXPECTED RESULT
Seeing a outline

SOFTWARE/OS VERSIONS
Software: Krita 4.2.0 Pre-Alpha git 402c41c
Windows: Microsoft Windows 10 Home - Version	10.0.17134 Build 17134

ADDITIONAL INFORMATION
SVG made in Inkscape 92.3 near the latest version of that branch. Possibly almost 1.0.

Clarification

On the outline of observed - there's just basic information. No visible stroke.

On the expected, there should be visible outline.

More information - The workaround to this issue to set the vector blending mode into normal, and Krita is able to open it just fine.
Comment 3 reptillia39 2019-01-16 18:29:22 UTC
IRC comment - can you include in the bugreport how svg supposed to look like, for reference?
----
Reply - The SVG contains only a single line with a thin outline.

The relevant part of the svg is:

    <filter
       inkscape:collect="always"
       style="color-interpolation-filters:sRGB"
       id="filter852">
      <feBlend
         inkscape:collect="always"
         mode="exclusion"
         in2="BackgroundImage"
         id="feBlend854" />
    </filter>
