CrashReporter itself keeps crashing

I never get crash logs when an application crashes, and the reason is that CrashReporter itself crashes:

4/20/12 10:11:25 AM com.apple.launchd.peruser.501[104]
(com.apple.ReportCrash.Self[133]) Job appears to have crashed: Trace/BPT trap

A google search shows that I'm not the only person to experience this. But I haven't found a definitive cure. A popular google hit suggests moving the LaunchAgents .plist file from the System LaunchAgents to the User LaunchAgents, but that made no difference for me. I'm wondering if anyone has actually solved this.

(This is on Snow Leopard. I have a Lion installation and another Snow Leopard computer; the problem doesn't occur there. It's just this one volume.)


try these two things:

  1. boot to safe mode, and then reboot. (hold Shift at system chime)
  2. boot to single user mode, delete /Systems/Library/Caches & subdirectories

fixed lots of crash reporter errors on my machine.
