I can unlock the system by switching to a different virtual console and kil= ling lldb, but that obviously stops the debugging session.=20=20 Anyways, this is what I've been able to glean so far: Process 35829 stopped * thread #1, name =3D 'xscreensaver-aut', stop reason =3D signal SIGSEGV: i= nvalid address (fault address: 0x0) frame #0: 0x000000080066fe84 libc.so.7`strlen + 84 libc.so.7`strlen: -> 0x80066fe84 <+84>: movq (%rdi), %r11 0x80066fe87 <+87>: leaq (%r11,%r8), %rcx 0x80066fe8b <+91>: notq %r11 0x80066fe8e <+94>: andq %r11, %rcx ((lldb) Terminated (Terminated here is when I kill lldb from the virtual console). --=20 You are receiving this mail because: You are on the CC list for the bug.=
