[BioC] virtualArray: Error at second execution of virtualArrayExpressionSets

Dear virtualArray maintainer,

I'm facing the following problem.

When I run "virtualArrayExpressionSets" on a few expression sets in a clean R session it works fine,
but if I'm running the function again the exact same way in the same session it gives me the following error:

##Error
"""
Error in LastError$store(results = results, is.error = is.error, throw.error = TRUE) : 
  Errors occurred during execution. First error message:
Error in as.character.default(x): no method for coercing this S4 class to a vector
"""

##Code for calling the function
data.combined  <- virtualArrayExpressionSets(
all_expression_sets=c(eset.A,eset.B,eset.C,eset.D),
identifier = "SYMBOL", 
collapse_fun = median, 
removeBatcheffect = "EB", 
sampleinfo = FALSE)


I'm probably overlooking something obvious, so any comments are much appreciated.

Thanks a lot!

Best,
Adrian
