This can be found in the logs:

So I suspect there is a bug somewhere in the stack.
Hi Arturo, it does look like there's something fishy from the "Invalid string
length 1869348864" (which looks way too high). Is that reproducible everytime
? Is there something specific/peculiar about your installation? I assume
you're using light-locker as your screen locker?
Hi there,
I have experienced the same problem in 2 different systems.
However, I have the strong suspicion that this happened in the same context:
upgrading the system.
I need a few more days to pass by, but I have the hunch that after a reboot this
problem goes away. I didn't see it happening again after being hit by it those 2
times in a row (which triggered me to open this bug).
To your question: yes, I'm using light-locker.
Thanks for the follow up, I'll keep you updated in the next few days.
