Public bug reported: Gnome shell crashes reliably and only after a period of inactivity (15+ minutes). I have not seen it crash while using the desktop - even for hours at a time. I suspect it has something to do with locking the screen or turning off the monitor. However even after attempting to disable both lockscreen and blank screen it still happens.
After a crash dmesg shows [ 3726.608957] gnome-shell[2666]: segfault at 38 ip 00007fc6a7330c30 sp 00007fff0d12fe78 error 4 in libmutter-1.so.0.0.0[7fc6a72de000+141000] When the crash happens it goes back to the login screen. Logging in works fine. It happens pretty reliably but will sometimes successfully lock and blank the screen. I would say it happens 90% of the time I leave the computer alone for awhile.
