Bug with node corners at display or export to bitmap

[Alexis Pautrot]

Hi,

Despite being the best vector program, I have encountered a bug that is really annoying.

Hard to explain with words (English not my mother tong), but easy to reproduce with the attached file.

When using node corners in the provided arbitrary shape, there is a bug at display or when exporting to bitmap.

To reproduce the bug, in the attached file, select the shape, then group it (with itself, I know that sounds stupid). The shape will display with a bug. To get rid of the bug, I had to change the anchors of the corner to change the curvature (the corner under the red dot).

I'm using Inkscape v0.48.1.0, 32bit.
I'm using Windows 7, 64 bit.

Regards.

- Reproduced with Inkscape 0.46, 0.47 on Mac OS X 10.5.8 (32bit) and 0.48.4 on OS X 10.7.5 (64bit)
  (in all stable versions, changing the zoom level restores the correct rendering of the path)
- Not reproduced with the new renderer in trunk >= r10326
  (fixed with the merge of the cairo-rendering branch)

Grouping a single object doesn't sound stupid at all - there are plenty of use cases where this is helpful (for example, to blur the clipped edged of an object, apply more than one clippath/mask to an object, or to allow adding objects to a clip later on without having to release it first):
