[Bug 849600] Re: gnome-screensaver crashed with SIGSEGV in g_main_context_dispatch()

 

No Screensaver set, Screen seems to blank anyway after about ten
minutes, no way to switch it off in Settings. When playing a video, even
when the player is set to inhibit screensaver during playback it blanks
anyway. Don't know if this is related to this crash which occured after
swiping the mouse to bring back the screen but it bugs the hell out of
me so  thought I i'd mention it anyway...

Title:
  gnome-screensaver crashed with SIGSEGV in g_main_context_dispatch()

Status in “gnome-screensaver” package in Ubuntu:
  Confirmed

Bug description:
  Opening a new bug because this seems to be the first Oneiric beta1
  instance of the bug. I run gnome-shell, and I was unable to log back
  in after the screen locked. Running gnome-shell --replace from a
  virtual terminal allowed me to unlock the screen. I don't believe it's
  a security issue because I still was required to enter a password to
  get back to my session.
