Hello ,
This is the second time happening , at the first time I thought it simply
crashed because whatever happened to it ,
But when it happens (I am not at keyboard when it happens) , I see 2
notifications , the first one that pop-up has crashed , the second one
mate-screensaver has crashed , and I have no prompt for password when both of
them crash

I have the crash files if you need them , Or you could tell me what exactly you
need from me or how to send you the dump crashes and whether they contain
private information or not , please tell me
I set this as Security risk because once it crashes , you are free to go with
the PC , and I don't know if someone manages to crash it will be able to bypass
the login screen.
Screensaver crashes and it allows you to have control over the PC with
no need for password or anything else.
