[BioC] error in ls() unused arguments

Dear all,

I encountered a problem while working on R that I do not know how to solve.
It started when I wanted to load the affyPLM package:
*/> library(affyPLM)
Loading required package: gcrma
Loading required package: matchprobes
Loading required package: splines
Loading required package: preprocessCore
Error in ls(where) : unused argument(s) (2)
Error in library(affyPLM) : .First.lib failed for 'affyPLM'/*

As packages such as 'affy', 'genefilter' and 'limma' load fine, I 
thought it might be something related to the affyPLM package.
However, upon trying to re-install the package, I got a similar error:
/*> source("http://bioconductor.org/biocLite.R")
Error in ls(all.names = TRUE) : unused argument(s) (all.names = TRUE)*/

Now, I think it may be related to the 'ls' function. Strangely enough, 
when using the 'ls' command I get this:
/*> ls()
Quality control information for mouse4302:
This package has the following mappings:
Error in get(mapname) : variable "mouse4302ACCNUM" was not found*/

I can now only access my objects using 'objects()'.
Strangely, I have been using  all week without problems. I have tried 
restarting R, even reinstalling R, but to no avail. I hope it is 
something stupid I do not see.... Does anyone have a suggestion how I 
can solve this?

Any help would be greatly appreciated,

Patrick
