I've spent some time at this bug, running automated and random input tests to try reproduce it. I've found 1 probable cause for this issue: url-dispatcher starts apps if they're not running - and it appears to be possible that AppMan is told to respawn the same app around the same time - causing 2 instances of the same app to be executed - one of which AppMan will reject. I had this happen once anyway.
I suspect there's another issue causing this bug too (going by log file output anyway). Am still investigating. So far, I've been unable to reproduce any user-facing fault related to this issue - AppMan is only rejecting a second instances of an app running. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtubuntu in Ubuntu. https://bugs.launchpad.net/bugs/1365673 Title: /usr/lib/arm-linux- gnueabihf/qt5/bin/qmlscene:6:qt_message_fatal:QMessageLogger::fatal:UbuntuClientIntegration::UbuntuClientIntegration:UbuntuMirClientIntegrationPlugin::create:loadIntegration Status in Qt integration with the Mir display server: Triaged Status in QT Ubuntu: Triaged Status in “qtubuntu” package in Ubuntu: Confirmed Status in “unity8” package in Ubuntu: Triaged Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding qtdeclarative-opensource-src.
