unity-settings-daemon crashes every time T450s laptop is un-docked

[Christopher Barrington-Leigh]

Every time I undock my Lenovo T450s from its superdock, unity-settings-daemon crashes (producing a crash dialog) and various things stop working as a result, e.g. some of my keyboard shortcuts, functionality on the OS status bar/panel, and normal shutdown.

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

Now open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.

you can also follow http://wiki.ubuntu.com/DebuggingProgramCrash to get a backtrace using gdb

Curious.

I have submitted this bug report the automatic way more than once per day for the last 60 days: every time I undock, a dialog comes up and I say yes to submit it. But I never get an email saying there's been a bug report generated, and I've never received any follow-up.

/etc/default/apport says (already):
enabled=1

running ubuntu-bug on the crash report ( /var/crash/_usr_lib_unity-settings-daemon_unity-settings-daemon.1001.crash ) brings up the dialog I see every day; I click Continue, and it goes away, and nothing more happens.

well, then it's likely registered on http://errors.ubuntu.com, that doesn't give us which report it's matching. You could get the info from settings->privacy which has a link to open the issues you reported

[Christopher Barrington-Leigh (cpbl)]

The top one listed is:

2016-05-12 18:05 2016-05-12 19:05 UTC Crash unity-settings-daemon

I click on it and get:

"Sorry, you are not a member of a group that is allowed to see the data
from error reports. Please fill out this form to request access."

even though I obviously have a launchpad account.

The form is really over the top and it says eventually
"Thank you for submitting this request.
We will be in contact soon."

Oh, Canonical.

In case you can see it more easily than me, this is the link to that last bug report, which it said I'm not allowed to see:
