Crash after optimizing Inkscape (.91) code filter-gaussianBlur-deviation

[Roul P.]

Inkscape (not v0.49) created some trash style-code like this
style="filter-blend-mode:normal;color-rendering:auto;color:#000000;isolation:auto;mix-blend-mode:normal;filter-gaussianBlur-deviation:0;shape-rendering:auto;solid-color:#000000;image-rendering:auto"

(Scour is too old to recognize this code so we use some other...)

Some SVG optimzer can convert this code to SVG (XML) attributes like this

<path id="k" d="m213 368v9m-89 42v12m0 18v11.4m0-67.4v10m0-36v10m-43 58v9.469m0 76.5v10m0-38v10m0-40v12.5m-45-26.5v10m0-40v12.2m0 47.8v11m0-97.38v10.39m0-36v10m132 28v10m0-34v8.1m45 3.9v10" stroke="#000" stroke-width="4.5" fill="none" color-rendering="auto" isolation="auto" mix-blend-mode="normal" shape-rendering="auto" image-rendering="auto" filter-gaussianBlur-deviation="0" filter-blend-mode="normal" color="#000" solid-color="#000000"/>

If this code is present, Inkscape can't open this file anymore and crashes on this command filter-gaussianBlur-deviation="0" (without any messages, how I can get an error-log?)

Tested on Win7-x64 and Linux Mint

Replicated the crash with Inkscape 0.92.4, but 1.0beta2 (969f793, 2020-01-16) and 1.1-dev (12e2a09, 2020-02-19) don't crash anymore. Please reopen on http://inkscape.org/report if the problem occurs again.
