+{UD} You are using an outdated copy of the DB_File Perl module.  In fact db-2
+finally removed the handling of zero-sized keys which was one of the features
+tested by the old Perl testsuite and therefore you see an error.  But this
+never was documented and guaranteed, only broken programs used this feature.
+
+Consequently db-2 does not need to support this feature and instead signals
+an error which leads to easier debugging.  The DB_File module maintainer
+Paul Marquess <pmarquess@bfsec.bt.co.uk> acknowledged this change and fixed
+the testsuite so that if you use DB_File v1.60 or later you should not have
+any more problems with db-2.
