compiz crashed with SIGSEGV in unity::QuicklistView::ShowQuicklistWithTipAt()

[Edward Donovan]

I have experienced this crash several times, under Unity 6.10 and 6.12. Each time, I think, it's been triggered by using the Launcher's workspace switcher. Compiz relaunches succesfully (after some delay). I think this is probably a dupe of bug 972616, but I'd like to see the retracer go to work on it.

I deleted the xsession-errors file, as it had a lot of filenames and other information in it, and only these relevant lines:

  gnome-session[5060]: WARNING: Application 'compiz.desktop' killed by signal 11
  gnome-session[5060]: WARNING: App 'compiz.desktop' respawning too quickly
  gnome-session[5060]: CRITICAL: We failed, but the fail whale is dead. Sorry....

which seem like no surprise.

Thanks.
