What is the name of the RRD file? Using basic * wildcarding, is it
databases.*.rrd or database.*.rrd - the RE above leaves that ambiguous
because '.' will match any character not just a dot. If it is in fact
database.*.rrd that could be the problem.

I had a similar issue a while ago - see
http://www.hswn.dk/hobbiton/2009/05/msg00149.html

In a nutshell, trends seems to require a file to exist of the form
'graphname.*.rrd', but it doesn't have to be a real RRD file!
