[Bug 1267510] Re: qmltestrunner crashed with SIGSEGV in QSGTexture::setFiltering()
What makes you think it's UITK? I don't see any reasoning in the
description and the backtrace is Qt only.
** Changed in: ubuntu-ui-toolkit (Ubuntu)

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.
