Title:
  Document Viewer app freezes/crashes on clicking back from pdf files

Status in Canonical System Image:
  Confirmed
Status in Ubuntu Document Viewer App:
  Confirmed
Status in ubuntu-ui-toolkit package in Ubuntu:
  New

Bug description:
  Device: mako
  Channel: rc-proposed

  App freezes every time on clicking back arrow when trying to close pdf files and go back to the documents list.
  The only solution seems to be closing the app every time I want to open other pdf.
  On some occasions, the app will crash by itself when getting out of an pdf.

  [EDIT]:
  Former DocViewer contributor Stefano Verzegnassi took a look at this bug so I'll just paste his response here:

  I've found a few minutes for having a look at this issue, and I guess
  this has nothing to do with Document Viewer. The component which
  causes the issue hasn't received any update since an year.

  The issue in the DocViewer seems to be the same described in bug
  #1568016, which sounds to me as a regression in the UI Toolkit.

  During the last months a lot of regressions have been introduced with any UITK update, because critical changes are directly committed to a stable target.
  As long as core apps should always target the latest version of the toolkit, it should also be granted that a new toolkit update does not break any core app functionality.

  Anyway, since the UITK team is actually rewriting many components, I
  suspect the faulty component of the PDF viewer should be entirely
  rewritten too, since there's a small chance the issue gets fixed
  upstream (and that's what they did with the issue at the link below).

  I'm no more an active contributor of the Ubuntu Document Viewer, and
  whoever will join the team should also take care of fixing this.
