Bug Description

I can reproduce this bug both on the development and stable images, on the Nexus 4.

The core file is at https://errors.ubuntu.com/oops/55b25b5c-55f4-11e5-be0c-fa163e4ccdf2
And the unity8.log is here: http://paste.ubuntu.com/12312447/
(I added the blank lines, ignore them)

The crash happens after a trusted session is closed, but that might be coincidental. The scenario to reproduce it is a bit complicated:

- Build and install the facebook webapp from lp:~mardy/webapps-core/post-error-feedback/
- Run it, and make sure that it logs in (create/authorize account as needed)
- From the browser (even from the desktop) navigate to https://www.facebook.com/settings?tab=applications and revoke access to the "Ubuntu" application
- Open the gallery, tap on a photo and choose the "Share action"
- Choose the Facebook app as share destination
  (focus moves back to the Facebook app, an upload form appears)
- Write anything in the test area, and clik the "Post" button
  (After a few seconds, a trusted session will appear, asking you to grant permissions to the app)
- Grant permissions to the app
  (the trust session closes)

At this point, unity8 will restart.

I just reproduced it after logging in my Ubuntu One account from the dash (when installing an app).

From the log it looks very similar to what happens in bug 1492185.

Meaning that they likely share the same cause and fix (fingers crossed).

@mardy could you please check if the packages from comment #4 fixes this bug?
