Bug#874727: closed by Anton Gladky <gladk at debian.org> (Bug#874727: fixed in coin3 3.1.4~abc9f50+dfsg2-1)

[mlampert]

I've attached an xml tool table.

* start FreeCAD from the command line
* Create a new document
* switch to "Path" Workbench
* start "Path Manager" from the Path menu
* import attached tooltable (note the file type selection)

You'll get:
Program received signal SIGSEGV, Segmentation fault.

I don't think the file itself matters at all because it segfaults while trying to initialise libexpat, but in case the attachment gets filtered, this is the content:
