Comment:

 I am using libpurple alone and it is hard for me to get the debug log.
 basically a gloop fires events in my code (including libpurple events), so
 my code was busy handling other events and the read from the pipe is lost.
 Basically this line failed in resolved in dnssrv.c:

 if (read(source, &type, sizeof(type)) == sizeof(type))

 thus the callback is never fired.
