Our local Ubuntu developer and guru explained to me:

 | Ubuntu has a special program ("apport") to detect crashes and report
 | information about them (including stack backtraces) to the Ubuntu issue
 | tracker.
 | 
 | The kernel has a sysctl variable to support this called
 | 
 |   kernel.core_pattern
 | 
 | if set to a string starting with '|' then it invokes the named program
 | instead of writing the core to the named file.  The kernel default is
 | 'core'.
 | 
 | You can check with 'sysctl kernel.core_pattern'.
 | 
 | Ubuntu sets this to redirect crashes to their special handler program.
 | 
 | If you set it back (see /etc/sysctl.conf or "man sysctl") to "core" and
 | set "ulimit -c unlimited" then you'll get core files in the current
 | working directory when a program crashes.

But I am not running Ubuntu myself...
