local cat = pdffile:getCatalog()
local pg = cat:getPage(1)
local pgc = pg:getContents()

local stream = pgc:getStream()

works better for me, but this is just a wild guess

fixed in trunk, SVN 3792, many thanks for the correct patch.

Btw, there is no function like stream:getLength() (yet).

stream:getChar() works, also on the undecoded stream, like
local ustream = stream:getUndecodedStream()
