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.
