[Bug 1531804] [NEW] [desktop] Browser crashes when downloading a file
Public bug reported:
Steps to reproduce:
- on a desktop setup (xenial from the repositories, or wily from
https://launchpad.net/~osomon/+archive/ubuntu/webbrowser-app), with
qtdeclarative5-ubuntu-content1 and qtdeclarative5-ubuntu-download-
manager0.1 installed, run webbrowser-app, point it to a page that has a
link to e.g. a PDF document (e.g. https://help.ubuntu.com/), and click
that link
Expected result: the file is downloaded
Current result: crash with the following stacktrace:
