Lock screen, notifications panel crashes

[Charles Birk]

Multiple issues:
1) Lock screen crashes revealing the desktop after sleep/wake

2) Notification panel crashes constantly (with ubuntu-mate)

3) Ability to send report fails for whatever reason

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

Hi Daniel,

Thanks a lot for your quick response!

Here are links to the recently crashed items (i do not have access to see them but requested access):

November 19: https://errors.ubuntu.com/oops/ecc421e6-ebfc-11e8-94e9-fa163e102db1

November 17: https://errors.ubuntu.com/oops/a30a669e-eadc-11e8-973e-fa163ee63de6

There are a few more but the errors are most probably the same.

Let me know if I've missed anything.

Thanks!
