Comment 9 for bug 388873

The job's cause (event that caused it to start/stop) is invalid, this causes the segfault

(gdb) p job->cause
$26 = (EventEmission *) 0x9a0eb48

(gdb) p *job->cause
$17 = {event = {entry = {prev = 0x9a0eb10, next = 0x9a0dd18},
    name = 0x8 <Address 0x8 out of bounds>, args = 0x9a0eb00,
    env = 0x9a0eb58}, id = 161540952, progress = 134517312, jobs = -1,
  failed = 1918989427}

(gdb) p *job

There are two events in the list:

(gdb) p *((Event *)events->next)
$24 = {entry = {prev = 0x9a0e1f0, next = 0x9a0ec98},
  name = 0x9a0d938 "stopped", args = 0x9a0e400, env = 0x0}
(gdb) p *((Event *)events->next->next)
$25 = {entry = {prev = 0x9a0dc68, next = 0x9a0d9a0},
  name = 0x9a0e2e8 "restart-bgr", args = 0x0, env = 0x0}

(gdb) p *((EventEmission *)events->next)
$27 = {event = {entry = {prev = 0x9a0e1f0, next = 0x9a0ec98},
    name = 0x9a0d938 "stopped", args = 0x9a0e400, env = 0x0}, id = 242,
  progress = EVENT_HANDLING, jobs = 1, failed = 0}
(gdb) p *((EventEmission *)events->next->next)
$28 = {event = {entry = {prev = 0x9a0dc68, next = 0x9a0d9a0},
    name = 0x9a0e2e8 "restart-bgr", args = 0x0, env = 0x0}, id = 245,
  progress = EVENT_HANDLING, jobs = 1, failed = 0}
