(this only happens when the libdbi driver is actually used the first time!)
This is KNOWN to be the case with RHEL4 and FC4 and FC5! (But actually this is a bug with libdbi make files!)
+* at least version 0.8.1 of libdbiexhibits a bug with BINARY fields
+ (shorttext,text,mediumtext,longtext and possibly also BINARY and BLOB fields),
+ that can result in coredumps of rrdtool.
+ The tool will tell you on stderr if this occures, so that you know what may be the reason.
+ If you are not experiencing these coredumps, then set the environment variable RRD_NO_LIBDBI_BUG_WARNING,
+ and then the message will not get shown.
