src/caencoder.c:1949: ca_encoder_initialize_name_table: Assertion `!n->name_table' failed #169

When running casync make I receive the following error:

casync: ../casync-2_p20180321/src/caencoder.c:1949: ca_encoder_initialize_name_table: Assertion `!n->name_table' failed.
make: *** [Makefile:14: gentoo_kibana_base.caidx] Abgebrochen (Speicherauszug erstellt)

This only happens for one of the machines stored in the shared storage.

Running on Gentoo.

Deleting the .cacac directory fixes this but I'm sure this error is not intended in the first place... What may have happened: The machines are clones (generated with machinectl clone, and maybe even one was cloned while casync make -c was running. But I think the cache directory should be transaction save, or simply discard what smells fishy...
