Status changed to 'Confirmed' because the bug affects multiple users.

Just performed apt-get update , upgrade, dist-upgrade. Launched Thunderbird (thunderbrowse installed) clicked on an email link to launch browser tab and this accured. TBird kept working, and I completed reading in thunderbrowse which is configured to run Chromium

That seems quite a frequent issue on errors.ubuntu.com, not sure but could it be a problem on logout? In which case we should maybe just catch the error to avoid having apport triggering for users on next login...
