This happens when media-hub-server has crashed or become unresponsive in some way, either because the current player session over dbus has hung or because the system load is very high for some reason. Can you clear out the crash files in /var/crash, then the next time you notice this do the following:
1. Attach the crash file(s) for media-hub here 2. Attach the media-hub log file from /home/phablet/.cache/upstart/media-hub.log 3. See if you're able to play music from music-app when you're getting these messages. ** Also affects: media-hub (Ubuntu) Importance: Undecided Status: New ** Changed in: qtubuntu-media (Ubuntu) Status: New => Invalid ** Changed in: media-hub (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1613056 Title: unity8.log spammed: Failed to get current playback position: org.freedesktop.DBus.Error.UnknownMethod: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist Status in media-hub package in Ubuntu: Incomplete Status in qtubuntu-media package in Ubuntu: Invalid Status in unity8 package in Ubuntu: Invalid Bug description: BQ E5, OTA-12.
