    Description

      OS X 10.10.5. Two internet connections: Wifi and Thunderbolt Ethernet. "Auto Proxy Discovery" in Ethernet's proxy settings is checked.

      When I start my application I get a freeze as main thread is blocked by: 

      CFURLCreateDataAndPropertiesFromResource(kCFAllocatorDefault, pacUrl, &pacData, NULL, NULL, &errorCode)

      inside 

      macQueryInternal(const QNetworkProxyQuery &query)

      (qnetworkproxy_mac.cpp)

      pacUrl is set to http://wpad/wpad.dat.

      Unselecting "Auto Proxy Discovery" in Ethernet proxy settings solves the problem.
