Bug#860171: dia: Clockwise curved arrows are reset into straight lines

[eingousef <eingousef@gmail.com>]

Package: dia
Version: 0.97.3+git20160930-5
Severity: important

Dear Maintainer,

Create a diagram with dia and put some curved arrows (arcs) in it,
clockwise and anticlockwise. Save the file, close it and open it
again: the clockwise curved arrows are now straight.

This is freaking annoying.

This might be related to bug #788727

Regards,
