Hi there, Apparently there is a bug in DefaultMainLoop destructor - kinda deadlock is caused when a mutex is being tried to lock twice in the same thread. pthread's manual says pthread_mutex_lock()'s behavior is undefined for such scenario if the the mutex was initialized with PTHREAD_MUTEX_DEFAULT (which is the case in DefaultMutex). In my case it was clients getting stuck. The attached patch also contains a fix in xml2cpp that I already submitted once, when dbus-c++ used to be hosted on wengo. For some reason I realize that it was never applied. I would appreciate if it was done now. Thanks. -- Regards, Sergey
