[BioC] rbind in annaffy problem

I am having a problem with rbind in annaffy. I have a very simple
annaffy table that, for the sake of illustration, I have tried to
duplicate by row binding to itself (this is a simplification of a more
complex problem).

Here is my code:

GO.TERM=common.go.hyper$"GO ID"[i], GO.Desc="GO Term")

bound<-rbind(affytable.temp, affytable.temp)

and the output:

> bound


I do not have this problem with merge, which works just fine.

SessionInfo (with all packages just updated):

R version 2.2.0, 2005-10-06, i386-pc-mingw32 

attached base packages:
[1] "splines"   "tools"     "methods"   "stats"     "graphics"
"grDevices" "utils"     "datasets"  "base"

   "1.10.2"    "1.7-3"

Could this be a problem with R losing track of which "rbind" function to
use (i.e. generic or annaffy), is annaffy broke, or am I doing something
