Bug Description

Unlike other bugs where parts of paths disappear, exporting a letter-sized image at 300dpi distorts most stars that have
* 6 corners
* spoke ratio 0.010
* rounded -10.000
* randomized: 0.000
* size: < 1inch (may affect other sizes)
causes a distortion by which the bottom of the stars seems to be pulled left. Different DPIs seem to have different degrees of distortion, and exporting smaller sections causes no problems.

The distortion happens occasionally with the on-screen rendering when the stars are nested and grouped together.

This affects 0.47pre1 on MacOsX 10.4 Intel, and 0.46-devel r21627 on Vista.

Attached is an image with the starts properly rendered, created by selecting them and exporting the "Selection"
The other image is a cropped section of a letter-sized image with more elements, exported as a "Page", showing the distortion
Both had the same settings of either 300 or 305 dpi.

could you attach the original .svg file?

This is a more compact version, eliminating almost everything else. The distortion still happens on export of the full page.

The rendered PNG.
