Freecad crashes while importing any .svg: 1. Open Inkscape 2. Save to "drwing.svg" or whatever (yes, empty file) 3. Launch Freecad 4. File -> New 5.

Sorry for the noise but I got 0.17 working... Not sure what the problem was (just reinstalled). The SVG import bug works as well in 0.17.

I noticed because PostGIS is affected via postgis B-D -> libsfcgal-dev -> libsfcgal-osg1 -> libopenscenegraph100v5 -> libcoin80v5. Looking at https://udd.debian.org/cgi-bin/autoremovals.cgi there's quite a few packages depending on coin3. So the question whether this affects freecad only or more packages is making quite a difference. Do you have a recipe on how to reproduce the bug with freecad from experimental? Christoph

Hi Christoph, it's a packaging bug - libcoin is statically linked with libexpat, and the version being used is outdated. So anything that uses libcoin and libexpat will run into a segfault. I am not aware of any other application that uses libcoin.

Hi, do we have any evidence that this is a bug in coin3, and not simply freecad being buggy? The freecad version currently in unstable crashes in all sorts of ways.

Are there any workarounds for this issue? Seems same problem as discovered on Kbuntu 18.04 that FreeCAD crashes when importing from SVG file.
