Gnome shell crashes when screen is locked

[elPraga]

When I lock the screen or put the computer to sleep, gnome-shell crashes. The crash might be related to extensions, as I was unable to reproduce the crashes when extensions were disabled.

Nontheless, Gnome-shell should not crash or be unable to wake up from suspend because of a faulty extension.

I'm not really sure if I am attaching the appropriate information, please, let me know if more information is needed. (please, mention also how to obtain it)

Thank you for your work!

with regards,

Tomas Kaluza

If the crash is due to a faulty extension then please report it to the extension author. But in case it's not...

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.
