I attach an example file (I pressed something and posted the issue prematurely - sorry).

It imports fine in FreeCAD 0.16 (stable) but break in FreeCAD daily 0.17.

When loading with v0.17 which may use occ7.0 then the following error occurs:


Traceback (most recent call last):

When loading with v0.16 which here uses occ6.8 no error occurs.

 I also experienced crash when importing .svg file. It was after an upgrade from Mint 18.3 to Mint 19 and I believe it is due to libexpat1 versions. From research I needed to downgrade the version, here what I did to fix it -

downloaded from https://pkgs.org/download/libexpat1
Ubuntu 17.10 versions
libexpat1_2.2.3-1_amd64.deb
libexpat1_2.2.3-1_i386.deb
then go to Download directory and install
sudo dpkg -i libexpat1_2.2.3-1_i386.deb
sudo dpkg -i libexpat1_2.2.3-1_amd64.deb

Note had to install 386 version first

Reboot & test - still crashes
Try agin with Ubuntu 16.04 versions
libexpat1_2.1.0-7ubuntu0.16.04.3_i386.deb
libexpat1_2.1.0-7ubuntu0.16.04.3_amd64.deb
This time I had to install amd64 version first

Tested - it works!!!

 Looks like this is related or a duplicate of 0003307
In that ticket thread it's reported that:

Dependency problem, Coin3d and Python use different versions of the libexpat library, cannot be fixed by freecad devel.

I'm going to resolve this ticket since it's an upstream packaging issue.
