And of course it can also be consistently reproduced with the Path > Break apart command.

Also reproduced with 0.91.
Seems to be related to the transform: scale() attribute. The bug doesn't occur when I break apart a path created with the pen tool, with no transform. But the same path is affected if I use the eraser instead of the Path command.

Thanks for the new patch!

It's a bit better, but not fixed yet:
- The stroke width still changes (20 mm before, 19,844 mm after).
- When using dashes, they are quite severely affected (not reproduced with 0.91).
