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.

Title:
  gallery-app crashes after a few seconds opened

Status in Canonical System Image:

Bug description:
  This happens using the new thumbnailer included in SILO 10, on the BQ.

  To install the new thumbnailer from silo 10:
  sudo apt-get update && sudo apt-get install thumbnailer-service

  To recreate just copy 2000 photo files to the Pictures folder and open the gallery-app. 
  After a few seconds it crashes is most cases.

  I've attached the .crash report obtained on the phone.
