Judging from the time it takes to call `QLocalSocket::waitForReadyRead` (1
second), the deadlock probably happens here (unless the code has changed after
the release):

Attached the DebugView output.
"QLocalSocket::waitForDisconnected() is not allowed in UnconnectedState "
appears rather frequently, it might be related.
