gst/gstregistry.c (_gst_registry_remove_cache_plugins): Lock the registry while we remove plugins.

Browse source 
Original commit message from CVS:
2006-01-17  Andy Wingo  <wingo@pobox.com>

* gst/gstregistry.c (_gst_registry_remove_cache_plugins): Lock the
registry while we remove plugins.

* tools/gst-inspect.c (print_element_info): Don't unref the
factory arg, that should be the responsibility of whatever code
received the ref. Fixes a double-free when called from
print_element_list via gst-inspect-0.10 -a. Fixes #327324.
(main): Unref the factory if we have one.
(print_element_list): No change -- relies on the
plugin_feature_list_free to free the list of features.
