That's just not how configuration in OVS works. When some part of the
configuration can't be implemented, ovs-vswitchd reports that, but it
doesn't change the configuration by removing anything.

Then there's a bug, either in the base code that you are working on, or
in some code that you have added. If you can figure out how to trigger
a segfault without code modifications, then I would be very interested
in a bug report.
