With the switch to the newer UFL version there components method on the combined space clashes with the new property on the UFL spaces with the same name.

Pickling of discrete functions 

A bug was fixed that could cause loading a pickled discrete function (space) to segfault. There might still be an issue with the backend methods, e.g., as_numpy, to be not added to a discrete function after load. This has been fixed but requires the JIT module to be rebuild. If you encounter this issue run `python python dune remove femspace ` and retry. Unfortunately the pickle files will also have to be regenerated…
