What makes you think it's UITK? I don't see any reasoning in the
description and the backtrace is Qt only.

Title:
  qmltestrunner crashed with SIGSEGV in QSGTexture::setFiltering()

Status in “ubuntu-ui-toolkit” package in Ubuntu:
  Incomplete

Bug description:
  This is a tricky one to reproduce, and might not actually be an issue
  in UITK, but then again - it might be.

  Steps:
  - pick up lp:~unity-team/unity8/new-scopes
  - merge lp:~unity-team/unity8/new-scopes-horizontal-card-layout
  - build it (see CODING)
  - bzr shelve --a qml/
  - cmake --build builddir --target testCard

  It doesn't happen under QML_BAD_GUI_RENDER_LOOP=1, so is some
  threading issue.
