 You should put that information in the PR (CC restored).

 Unfortunately, all I have are debugging suggestions...
 
  - Bring up a non-production machine to play with.
 
  - Bring up a virtual machine or jail to play with.
 
  - Start with a bare bones amd config (e.g., without anything
    but the default maps & .conf files).  If there's no core
    dump, then add back parts of your config until it dies.
 
  - Compile amd with debug on and turn up the debug level to
    see if you get any hints.
 
  - Trace deeper into the code to find the source of the null ptr.
 
  - Try asking on the am-utils mailing list.
