This looks OK to me.  When I try this (on a slightly older version) it gives expected results:
[alex at home /home/alex]$ rrdtool info all.rrd
filename = "all.rrd"
rrd_version = "0001"
step = 300
last_update = 978300900
ds[lommel].type = "COUNTER"
ds[lommel].minimal_heartbeat = 60
ds[lommel].min = NaN
ds[lommel].max = NaN
ds[lommel].last_ds = "UNKN"
ds[lommel].value = 0.0000000000e+00
ds[lommel].unknown_sec = 0
rra[0].cf = "AVERAGE"
rra[0].rows = 10
rra[0].pdp_per_row = 1
rra[0].xff = 5.0000000000e-01
rra[0].cdp_prep[0].value = NaN
rra[0].cdp_prep[0].unknown_datapoints = 0
[alex at home /home/alex]$

It should be able to work.  Check heartbeat (should be > 3600) and
make plenty use of rrdtool info and/or rrdtool dump when debugging.

Smart move :)
