# Original report text

Crash when creating a sweep.

# Additional information

OS: Linux Mint 17 Qiana
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.15.4484 (Git)
Branch: master
Hash: f72c802f5daa378298ffbfc3f3a17ec2d35c1816
Python version: 2.7.6
Qt version: 4.8.6
Coin version: 4.0.0a
OCC version: 6.7.1

# Steps to reproduce

Parts toolbox, select Sweep tool
Add Wire, Wire001, Wire002 for the sweep
Select the ellipse for sweep path
Create the sweep: crash

Probably I'm doing something illegal here by having the ellipse extend a little beyond the Wire and Wire002, but nevertheless it shouldn't crash.

Making it a complete ellipse solves the problem, it only crashes when the ellipse is an arc.
