Assertion fails in CopyModel when using multi-threading

[mhoff]

import nest
nest.SetKernelStatus({"local_num_threads": 10})
nest.Install("sporemodule")
nest.CopyModel("synaptic_sampling_rewardgradient_synapse", "reward_synapse")

fails with

python: /home/hoff/.sources/nest-simulator/sli/name.cc:89: unsigned int Name::insert(const string&): Assertion `not omp_in_parallel()' failed.

This appears to be a consequence of https://github.com/nest/nest-simulator/pull/739 in combination with multi-threading (local_num_threads > 1).
