I am writing a c program using the avahi api. Below is the code that is generating the error. owner->_client = avahi_client_new(avahi_threaded_poll_get(owner->_poll), AVAHI_CLIENT_NO_FAIL, ClientCallback, owner, &error); AvahiEntryGroup * group = avahi_entry_group_new(owner->_client, EntryGroupCallback, owner); if (!group) { fprintf(stderr, "avahi_entry_group_new() failed: %s\n", avahi_strerror(avahi_client_errno(owner->_client))); } else { ret = avahi_entry_group_add_service_strlst(group, AVAHI_IF_UNSPEC, AVAHI_PROTO_UNSPEC, 0, serviceName, regType, domain, host, port, txt); } When I step through the last call in my program is avahi_entry_group_add_service_strlst. Then I get the following stack dump from dbus. I have also see this happen from the avahi_entry_group_new call above. But if it makes it passed this one, it dies on the next one with the same dbus stack trace. #0 0xb7c176b6 in ?? () from /lib/libdbus-1.so.3 #1 0xb7c1709a in ??

Is this a known error (with a potential fix) somewhere? Thanks
