Bug#727784: freecad: Draft mode: Circle tool broken

[Dave Williams]

Package: freecad
Version: 0.13.2580-dfsg-2
Severity: important

Dear Maintainer,

I wish to report what appears to be a problem with the Draft workbench for freecad.

The bug is easy to recreate:
 - open freecad (I've been doing this by running 'freecad' in a 'konsole' terminal.
 - select the Draft environment (View->Workbench->Draft).
 - Attempt to draw a circle with the circle tool.
The expected outcome is a circle, however instead I get the following debug output:

I hope this is useful (and gets fixed soonish :-)). Please do not hesitate to
contact me if you need any further information from me/want me to test any patches
or similar.

Thanks for your efforts maintaining this package! It's appreciated by us end-users!

Best regards,
