Current values in HTML Summary pulling from wrong ds

I'm having a very curious problem with cricket 1.0.5, librrds-perl,
and librrd2 1.2.15 (from the packages in Debian etch).

Many target views do not display any text under "Values at last
update:". Other targets (especially ones with lots of fields) display
the Cur: value from the wrong ds (ds7's cur value will come from ds6,
ds6's will come from ds5, etc, assuming they're both GAUGE ds's).
Here's the kicker - the Avg and Max Values pull from the correct ds
and so does the graph.

When I try to browse one of these target views, I see this in Apache's
error log:

Use of uninitialized value in pack at
/usr/share/cricket/lib/RRD/Format.pm line 188.

If I run rrd-dump on an .rrd file, I get binary garbage in the PDP
line. Here's output from a simple one-ds rrd:

'rrdtool dump' output on the same rrd looks fine. Anyone know why?
