So, as best as we can tell, this is caused by an upgrade to Qt. Specifically, anything that uses QDBus is falling over. We are seeing similar problems with unity-scope-click here:
https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource- src/+bug/1618590 Basically, the code works with Qt 5.5, and doesn't with Qt 5.6. The ftbs for thumbnailer here https://launchpad.net/ubuntu/+source/thumbnailer/2.4+16.10.20160825-0ubuntu1 shows that the tests failed only on yakkety arm64 and ppc64el. That's because that silo was built before Qt 5.6 was added to the Xenial overlay. If I were to build in a silo now, I expect I'd see the same failures on both xenial and yakkety. Not sure what we can do to help here. The problem isn't in the thumbnailer code, but somewhere in QDBus, by the looks of things. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to thumbnailer in Ubuntu. https://bugs.launchpad.net/bugs/1613561 Title: [MIR] thumbnailer Status in thumbnailer package in Ubuntu: Incomplete Bug description: [Availability] * Available in universe [Rationale] * This package is required by many Ubuntu Touch applications and scopes, such as gallery app, music app, today scope, music scope, etc. [Security] * No known security issues at this time.
