I've been using the following snippet in my dissector for a while:

mime_dissector_handle = dissector_get_string_handle(
    media_type_dissector_table, content_type);

dissected = 0 < call_dissector(
    mime_dissector_handle, jxta_message_tvb, pinfo, tree);
but with recent builds it's segfaulting in call_dissector_work when there is no registered dissector matching the mime type in content_type. (NULL is passed to call_dissector() )
I'm a bit confused as to how this should work. Should I be checking the result of dissector_get_string_handle() for NULL? The docs seem to imply that I should be able to use call_dissector() with a NULL dissector handle and just get the raw data dissector.
