Bug Description

[Impact]
This is one of the top crashers on errors.ubuntu.com, and has many duplicates here. Releasing this fix in updates should make those counts go down fairly quickly.

[Testcase]
No easy way to test this and force it to happen. One should just check that it is still possible to log in to Ubuntu One, or Ubuntu Software Center, after upgrading and ensuring any existing ubuntu-sso-login process has terminated.

[Regression Potential]
Minimal. The back-ported change simply changes the main loop to use only GLib instead of GTK+ when the glib main loop is used for the back-end service, which was not necessary as the back-end process does not display any UI; and the GTK+
main loop is simply an extension of the GLib main loop to deal with initializing a connection to the X server and such.

That bug got around 900 reports on errors.ubuntu.com in 3 days this month, can we get the issue looked at for the LTS .1?

I was doing "sudo adduser --encrypt-home peter" when I got this bug.

Rodney, is there any chance you could catch that exception at least to lower whoopsie errors "noise" for the LTS users?

Set to verification-done after reading the code and testing that SSO still works correctly. As the code was switch to use a plain glib main loop, the X init calls that would result from use of Gtk+/Gdk main loop will not be called, and not result in this issue.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
