[BioC] Error using summary method on GOHyperGResult object

[Sim, Fraser]

Hi,

I have a new problem with R code that worked under R2.8.1. 

When I run in my code (too long to reproduce):
summary(hyperGTestresult) 

I get the error:
Error in if (nrow(df) == 0) { : argument is of length zero

Here's the result of:
>hyperGTestresult
Gene to GO BP  test for over-representation
1824 GO BP ids tested (149 have p < 0.001) Selected gene set size: 252 
    Gene universe size: 12474 
    Annotation package: hgu133plus2

So it looks like the hyperGTest worked and found some significant terms.

I can even extract the GO terms using sigCategories() and the pvalues
using pvalues() but the summary() and htmlReport() methods return the
same error.

I did not have this problem using the same code in R2.8.1.
