[Bioc-devel] graph file

[Kasper Daniel Hansen]

(fixing some Rgraphviz stuff).

If I do (in R)

library(graph)
g1_gz <- gzfile(system.file("GXL/graphExample-01.gxl.gz",package="graph"),
open="rb")
readLines(g1_gz)

I get

Warning message:
In readLines(g1_gz) :
  seek on a gzfile connection returned an internal error

but it seems to parse fine.  When I look at the file, say doing (in a shell)
  gunzip -t graphExample_01.gxl.gz
it seems to be in good shape.

Is there anyone who can hint at what is going on here?

[ The warning is in
  src/main/connections.c
in the R sources ]
