[Bioc-devel] BUG: conversion of IRanges DataFrame to data.frame raises error IFF AnnotationDbi loaded

H'lo,

I get this error:

Error in as.data.frame(DataFrame(a = 1)) : 
  could not find function "injectIntoScope"

when coercing a DataFrame to a data.frame, but only when preceeded by:

library(AnnotationDbi)

The following transcript demos in more detail.

Is there a workaround for me pending a fix?

Thanks!

Malcolm
