Unable to draft circle in current FreeCAD version

[Donjan Rodic]

Ubuntu 13.10 amd64, FreeCAD 0.13.1830-dfsg-3 .
This is already tracked in Debian (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=727784) and the fix seems to have landed upstream several weeks ago, but there's no new packaging or even mention on Launchpad that FreeCAD currently doesn't work properly.

To reproduce, open a new document, change to draft workbench, try to use the "Creates a circle" button. Terminal output:

Running the Python command 'Draft_Circle' failed:
Traceback (most recent call last):
  File "/usr/lib/freecad/Mod/Draft/DraftTools.py", line 843, in Activated
    self.arctrack = arcTracker()
  File "/usr/lib/freecad/Mod/Draft/DraftTrackers.py", line 328, in __init__
    self.recompute()
  File "/usr/lib/freecad/Mod/Draft/DraftTrackers.py", line 389, in recompute
    ivin.setBuffer(buf)
  File "/usr/lib/python2.7/dist-packages/pivy/coin.py", line 4692, in setBuffer
    return _coin.SoInput_setBuffer(self, *args)

Hitting the Cancel button adds this to the terminal output:

SoInput_setBuffer expected 3 arguments, got 2TaskDialogPython::reject: Circle instance has no attribute 'arctrack'

Drawing lines, paths and rectangles works. Drawing circles, arcs or polygons does not.

This bug is caused by a bug introduced in latest python-pivy package. A workaround has already been committed upstream and should be available with the next upgrade of the freecad package.

0.13.2800-dfsg-1 version has been uploaded to Debian Unstable a couple of
days ago.
