Dear Maintainer, I am not sure, if it was one of my daily upgrades which led to this. The last time it worked was on July the 31th. As I do not scrobble on a daily base I discovered this bug only last week, when I wanted to scrobble my last played songs. I am using a Cowon X7 player in MTP mode to scrobble from, if this is important for you to know. Steps to reproduce: 1. Connect your player to your computer 2. Start qtscrob 3. Wait that something happens 4. Click on the x of the window to close it You will see in the title bar, that qtscrob is not responding. If you click on x again, KDE's dialog with (roughly translated) "qtscrob is not responding" will appear ... :( If I start qtscrob from command line, I can see that it resets the USB bus, then tries it again and after connecting to it, I can see the number of songs with playcount out of X songs it found on my player. I do not see any error message nor warning at this point ... :( Sorry for the inconvenience and have a nice day Thomas.
