Actually, I hadn't. But trying it gave me the same "raveled" result:
>>> len(dl)
12
>>> map(len,dl)
[306, 306, 306, 306, 306, 306, 306, 306, 306, 306, 306, 306]
>>> x=ro.r['data.frame'](dl)
>>> len(x)
3672

Well, I don't know RPy nor Python enought, and maybe I misunderstand your
data structure, but did you tried the RPy corresponding to the R
function"as.data.frame(dl)"
