Title:
  qmlplugindump hangs at 100% CPU with qtorganizer5-eds

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

Bug description:
  I'm trying to build UITK on Manta

  Note I've installed the demo data with "phablet-demo-setup" <- might
  be related.

  Trying to build the UITK package natively on my tablet, with "dpkg-
  buildpackage -us -uc -j4" it hangs just after all test complete.
  Checking processes, I see "qmlplugindump" is running at 100% CPU
  usage, and nothing happens.

  I attached to the process and grabbed a backtrace - looks interesting:
