Public bug reported:
When I press the lock shortcut Gnome Shell won't lock screen: instead it
"blinks" (top bar disappears for a moment) and comes back, no lock
screen or password asked. Closing screen (laptop) does the same but I
still get low consumption, so hibernation seems to be working, but
1. I cleared /var/crash and then reproduced the bug: nothing was
created. Should I do something more?
2. I installed the "gnome-shell-dbgsym" package, the procedure to
generate a backtrace may take me some time so I'll do it later I'll add
it here ASAP
3. I use extensions, I try right now with an
3 (bis). I tried with a fresh new user, it worked as intended. I'll try
to disable all extensions to check if it's related to this, or another
configuration. Could the segfault come from something like this?

3 (ter). I disabled all extensions, then restarted gnome-shell, and now
it works well ;) nicely spotted, I feel ashamed I didn't think about
this first… Now I'll re-enabled them one by one, and give a report to
the faulty one's author. All good here I guess!
