Hang in _openProtocol::: when launching listener twice

[ghmrs356]

When I'm lauching a listener, shut it down and launch it again, the call to [listener open] never returns. It seems deadlocked with thread 6.

Complete backtraces of all threads below

Code to startup and shutdown

• (void)startup
  {
  if (browser != nil)
  return;

  browser = [[MYBonjourBrowser alloc] initWithServiceType:@"_rtxxxdata._tcp."];

  registration = [[browser myRegistration] retain];

  listener = [[BLIPListener alloc] initWithPort:12345];
  [listener setPickAvailablePort:YES];

  [browser start];
  [listener setDelegate:self];
  [listener open];

  [registration setPort:[listener port]];
  [registration start];
  }

• (void)shutdown
  {
  [browser stop];
  [registration stop];
  [listener close];
  [listener setDelegate:nil];

  [browser release], browser = nil;
  [registration release], registration = nil;
  [listener release], listener = nil;
  }
