I think I got it fixed now. The new version is 0.5, in the same place as before:

http://kmarkku.arkku.net/Path_crop_files/Gimp_master.html

Please report if any more errors occur. In the previous version I had overlooked the possibility that a splitting point may fall on an anchor of the path. I hope I got it now right, but it is rather complicated and I may still have missed something.

I know one more a little disturbing behaviour. A stroke, if it meets the cropping circle, is divided into two strokes even when that would not be necessary. I may do something about that in the future, or then I may not...

1. Path to selection from the red path.
   
2. Call the new plugin "crop path by general selection" (choosing the inside-outside option to be "both").

It seems to work correctly though it is slow. Please report any erronous behaviour.

As an example I use the Truchet path. Here I have drawn an additional path (red) from which to make a selection.



I did:

1. Path to selection from the red path.
   
2. Call the new plugin "crop path by general selection" (choosing the inside-outside option to be "both").
   

I got two paths. Here I display them separately. The red path does not belong to the cropped paths.





The input "Threshold" is meaningful if your selection is feathered.

In complicated cases the plugin is slow (the above run takes some 31 seconds), which is mainly due to the large number of calls to image.selection.get_pixel(). There may be some way to restrict that number of calls, but that would require further complication of the code. And it may not be so efficient after all. Currently I am not willing to try it. Going now to another project. Happy for having finished this. Please have fun.

Edit: I think I found the reason for the first error. As for the second error, is the path the same checker, only denser? If so, then perhaps the error too comes from the same bug. It will be fixed in the next version where I hope I shall have also incorporated what Ofnuts just taught me.
