RRD graphs appearing in trends but not in Devmon columns?

It's definitely an issue in the TEST2RRD parsing. As soon as I remove
"=devmon", the graphs appear. But when it's removed, the rrd files
aren't updated.

I'm guessing 4.2.3-RC1's "lib/hobbitrrd.c" needs to be altered, but
I'm not sure how -- the lines from hobbit-4.2.0-devmon-complete.patch
are present in it, and the same text is in 4.3.0's lib/hobbitrrd.c in
svn. Or perhaps my rrd is incorrect, but that seems unlikely because
the graphs show in the trends column and display correctly. I have rrd
filenames like if_load.Gi0_0.rrd.

Until this month I was using '-extra-tests=if_load
--extra-script=$BBHOME/ext/devmon-rrd.pl' for [rrddata] in
hobbitlaunch.cfg, might that have a lingering effect?

Any advice would be appreciated.
