[R] Problem with package twitteR and converting S4 obj to data frame

Hi,

I wrote a simple script to retrieve an n number of followers for a given
user in Twitter. I used a sample of n=10 to test my script and worked
perfectly but once I started to changes n I started to get the following
error:

Error in list_to_dataframe(res, attr(.data, "split_labels")) : 
  Results do not have equal lengths

I have no clue why works fine with n=10 but for higher values fall over. Any
Suggestions?

Below is my script.

Thanks,

Alberto

library(plyr)
library(twitteR)

getuser <- getUser('altons')
count <- 50

UserFollowers <-userFollowers(getuser, n=count, session = getCurlHandle())

dffollow <- ldply(userFollowers(getuser, n=count, session =
getCurlHandle()), 
              function(x) c(screenName=x at screenName
					,name=x at name
					,statusesCount =x at statusesCount
					,followersCount=x at followersCount
					,friendsCount=x at friendsCount
					,TwitterBirth=x at created
					,description=x at description
					,location=x at location)
                          )
