slapadd: tools.c:494: bdb_tool_entry_put: Assertion `text->bv_val[0] == '\0'' failed.

I only tested with ldapadd, but at a glance I don't see what could be the difference.

The protocol Add operation doesn't run into that assert. Have only looked briefly at the code, but I guess entry_schema_check()'s params textbuf[0] (and textlen?) must be zeroed if they were filled with a message but entry_schema_check() returns success anyway. Don't know where (in which function) that should be done though.
