--- Comment #1 from snehal....@gmail.com ---
I am using Bluez-Qt on a platform which is acting as bluetooth audio sink. I
don't have exact steps to reproduce the issue, but the d-bus log I captured
clearly shows the issue. When playing a media track from bluetooth audio
soruce, sometimes the media track information (Title and Album) is empty
string. I have observed this on Samsung S8 Android phone.
Below is the log from d-bus monitor. It is clear that 2nd Track update is send
without Title and Album, BluezQt is overwriting the entry as NULL.
