Hi Daniel, Sorry for this late reply, I've been studying for college finals.
I followed your steps and here is the .crash file as requested. How I was able to recreate the crash multiple times: 1. Login 2. Open terminal, run sudo nautilus --> I get this error : Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused (nautilus:4129): Gtk-WARNING **: cannot open display: :0 3. Run su, login and run nautilus 4. Navigate to /opt/<some app folder> 5. Open a file and close it 6. Copy that file to my non root desktop (/home/hiruna/Desktop in my case) 7. Open the file normally from the non root user --> Immediate freeze ** Attachment added: "_usr_bin_gnome-shell.1000.crash" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1725932/+attachment/4993038/+files/_usr_bin_gnome-shell.1000.crash ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725932 Title: gnome-shell freezes randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1725932/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
