Yes, I think so. I'm still working on the underlying cancellation issue. It turns out that a bug in our code meant that a cancel() sent to the thumbnail actually didn't cancel. That's benign because, if a request isn't cancelled, it completes normally and the result is ignored when the request finishes. (It just means that the thumbnailer potentially does some work that it was asked not to do.)
After fixing the bug in our code so requests are indeed cancelled, I'm seeing major problems in both gallery and camera apps if there are lots of images and I scroll quickly through a bunch of thumbnails. It's not yet clear whether that is a thumbnailer problem or something at the QML widget level. We are in the process of tracking it down. At any rate, we won't land the cancel fix until we are sure that it won't break anything, so go ahead and land this gallery app change please. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gallery-app in Ubuntu. https://bugs.launchpad.net/bugs/1470109 Title: gallery-app crashes after a few seconds opened Status in Canonical System Image: In Progress Status in Thumbnailer: Triaged Status in gallery-app package in Ubuntu: In Progress Bug description: This happens using the new thumbnailer included in SILO 10, on the BQ.
