Spotted a bug with Polyline > Offset (OQ)

On the attached file (png image, link : http://nikel.ovh/~tukuyomi/oq_bug.png ), the white entity is a polyline (1 line, 1 arc, 1 line).
Using Polyline > Offset (OQ) with a big value (1100 in my case), I expect to get the green polyline.
What I have is the red one (also CPU is maxed for some seconds every time I move the mouse.)

There are known limitations with the current offset tool (using the clipper library) for very small or very large offsets (in relation to the original).
You might want to try Misc > Draw > Polyline Offset (Alternative) instead.
