Bug Description

I created two paths. One of them (call it B) had a path effect applied. For my test, it was bend path. I then did a difference on them. I expected Inkscape to use the version of B with the path effect applied. But it used the original version of B. There is no work around as Inkscape has no way to make the result of a path effect permanent.

I think Inkscape, if it detects a binary path operation (like Difference) involves a path with a path effect applied, should ask the user which version of the path should be used. This should be done for both paths involved.

Sample document. Run the path operation of your choice on the included objects. Edit (3.6 KiB, image/svg+xml)

Almost forgot, this is very similar to Bug #168127, but not the same thing.

This is not true - menu 'Path > Object to Path' makes a path effect "permanent" -> after this path operations work as expected.

Inkscape probably should default to using the path data of the applied path effect (instead of the path data stored as 'inkscape:original-d') for path operations (since this corresponds to the expected (visual) result of the path operation).
