Inkscape on Ubuntu crashes with identical process...

Bug Description

I converted a text object(with fill and stroke[1.75px]), and a linked offset(with fill, blur[2.1], rounded joins&caps, xml radius[3]) to paths, combined the paths in 2 pieces (original text paths, offset paths), then grouped the 2 pieces, centered it vertically and horizontally [ctl+shft+A] after selecting 2 pieces and background polygon shape(with fill and stroke) [alt+shft+left click]. I then selected the offset with the point selector and tried to adjust the blur at which point it crashed, I have duplicated this process repeatedly...

Inkscape version (taken from attached SVG file):
   inkscape:version=" r9886"

The bug description and steps to reproduce seem to omit basic information: the SVG file in question seems to have been handed-edited (or modified with a custom extension or an external application) - the trigger for the crash AFAICT is related to the internal stylesheet, which defines a custom style for the path with id 'register_glow' which references a filter effect not present in the file:


If that filter definition is present - e.g. by adding one with the same id to the <defs> section - the crash does not occur when changing the blur via 'Fill and Stroke' dialog:
       stdDeviation="1.0" /></filter>

Could you share the steps how the internal style sheet is created, and kept up-to-date with the properties in the style attributes of the individual objects?

Simplified test case attached

Steps to reproduce the crash:
1) launch with current trunk
2) open attached file
3) 'Edit > Find' -> search for 'register_glow' in 'Properties'
4) open Fill&Stroke, blur selected object
--> crash

Simplified test case attached which has missing filter definition added: no crash with same steps.

Looks completely fixed by your fix johanengelen. Is there a specific issue this bug should focus on now? (perhaps it's only been fully fixed in 1.0, which is what I've tested on)

Otherwise I'd vote to close (well, as part of bug migration to GitLab, we would close this issue and open new issues in inbox anyhow
