Title:
  segfault on start of live session in kactivitymanager / libqt5sql

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I've installed 15.10 Wily Werewolf to my USB stick via usb-creator and restart the laptop
  on boot, I'm asked for the language and if I want to install or try a live session
  I select try life session, the dialog disappears and the machine is frozen

  Next try:
  boot to selection dialog
  switch to console crtl+alt+F1 (takes a moment)
  issue alt+syreq+1 and alt+sysreq+t ... both answer "operation is disabled"
  switch back to X ctrl+alt+F7 & click try live session
  immediately switch back to console ctrl+alt+F1
  watchdog detects hard lockup a few seconds later
  see attached screenshot

  reproduced also in beta1 of wily werewolf ... a month ago I imagine
  the beta was still starting, as for bug #1492840. But I've reformated
  the stick meanwhile and cannot really guarantee, that I didn't confuse
  the multiple ISO's I tried in short time.

  version information:
  kernel 4.2.0-16-generic #19-Ubuntu (4.1.0-3-generic #3-Ubuntu)
  libqt5sql.so 5.4.2 (both)
  currently running Kubuntu 15.04 on the same hardware
