[BioC] [ggbio+GenomicRanges] auto-plotting GRanges in R-devel fails

[Paul Theodor Pyl]

Hi all,

I observe the following behaviour in my R-devel when I try to autoplot a 
GRanges with ggbio:

 > library(ggbio)
 > library(GenomicRanges)
 > autoplot( GRanges( Rle("10",1), ranges=IRanges( start = 1000, 
width=110 ) ) )
Error in start(range(object, ignore.strand = TRUE)) :
   error in evaluating the argument 'x' in selecting a method for 
function 'start': Error in .local(o\
bject, ...) :
   could not find function "unsafe.update.GRanges"
