The patch for the ticket https://fedorahosted.org/389/ticket/48746
;, introduced a regression.
This patch contained two parts:
1. Hardening of MR code to prevent a crash when index_create function
do not set SLAPI_PLUGIN_OBJECT
2. rewriting of the code looking for MR plugin that can handle a given OID
The Part 2 of the code was wrong because it did not take into
consideration old and new MR plugin style that register their indexer
create function in a different way.
The Patch for 48844 basically revert the second part of the patch 48746.
