Description
I have upgraded recently from 5.7.1 to 5.8.RC and I am seeing something strange now.
my application handles the debug log and i am getting the following log :
2016-12-30 07:52:33 [ DEBUG ] Log.cpp @ 29 - "\"Unexpected reply signature: got \\\"\\\", expected \\\"a{sv}\\\"\""

This is looping over and over every 10 seconds.
I tried to see where this was coming from and i got the folowing stacktrace :
>~"#0 qtMessageOutput (type=QtDebugMsg, context=..., msg=...) at /home/longchair/LibreELEC.tv/build.PlexMediaPlayer-RPi2.arm-8.0-devel/plexmediaplayer-long-libcec4/src/utils/Log.cpp:22\n" >~"#1 0x73b0f5ce in qt_message_output(QtMsgType, QMessageLogContext const&, QString const&) () from target:/usr/local/qt5/lib/libQt5Core.so.5\n" >~"#2 0x73bb0fe2 in QDebug::~QDebug() () from target:/usr/local/qt5/lib/libQt5Core.so.5\n" >~"#3 0x6e373b12 in ?? () from target:/usr/local/qt5/plugins/bearer/libqconnmanbearer.so\n"
So it looks that something is wrong with the connmanbearer dbus API calls and that will generate an endless error log.
We are using connman 1.33, but also tried 1.31 and gave me the same issue.
All this works fine with 5.7.
Let me know if you need any further information.
