Sometimes crash reports don't work reliably. I can confirm it failed to log a new bug for you: https://bugs.launchpad.net/~jstevz4teh1337/+reportedbugs?orderby=-id&start=0
Of course, you shouldn't be running 'gnome-shell --replace' normally unless it's already crashed beforehand. Had it crashed before you ran that command? Even still, it sounds like a dangerous way to restart the shell because the act of it restarting might kill your terminal which is now the parent of the shell. So restarting the shell like that could make it crash immediately, unless you also do: nohup gnome-shell --replace & Please answer the question in the previous paragraph and also try the above more correct command instead. -- 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/1716068 Title: Gnome Shell crashes randomly Status in gnome-shell package in Ubuntu: Incomplete Bug description: When using Ubuntu Gnome 16.04, it is common for gnome-shell to crash unexpectedly, especially when performing intensive tasks. I've found that I was able to replicate the error by following these steps: Download and install a copy of Ubuntu Gnome 16.04.2 in VirtualBox. Open a screen displaying App icons in a menu, such as the app grid in the Gnome Shell overlay or the Arc Menu Gnome Shell extension (https://extensions.gnome.org/extension/1228/arc-menu/). Install all the latest software updates from the Software Updater or Synaptic. Upgrading all the packages between 16.04.2 to 16.04.3 seems to over-load Gnome Shell and cause the crash in the middle of the installation process. This crash always seems to occur after opening a screen with app icons and I'm not sure why. I've attached my .crash file updated with a symbolic stack trace.I hope this info and my attachment proves helpful in fixing the issue.
