I found the cause for the crash.  locate from findutils 4.5.11 has
a bug which results in trying to dereference a NULL string pointer.
It happens because it neglects to check the string for being non-NULL
at one point in the source... which, unfortunately, can be hit easily.

Apart from a findutils update to 4.5.12, a temporary workaround is
easy:

  $ export LOCATE_PATH=3D/var/locatedb
  $ locate junk
  [...no crash...]

HTH,
