Short description of error
Normally in Blender the Delete key can be used instead of the X key to delete things. This does not work with curves created in sculpting mode. This is a usability problem for people used to the Delete key.

Exact steps for others to reproduce the error

1. go to sculpting mode.
2. Select "Curve" as "Stroke Method"
3. Draw a curve
4. Try to get rid of it after selecting all parts of it - it works with X, but not with the Delete key
