... 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'. After the new bug report with a crash file has been created, please comment here telling us the new bug ID. Please do not manually attach any crash files to bugs - only use ubuntu-bug (or apport-cli). ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1730748 Title: gnome-shell froze and crashed Status in gnome-shell package in Ubuntu: Incomplete Bug description: Cannot say much except that I had opened gnome-terminal and suddenly the session just froze and crashed.
