Hi, I noticed that on later distros (openSUSE 11.2 for example) I get this warning:
> DeprecationWarning: os.popen2 is deprecated. Use the subprocess module.
It looks harmless and rdiff-backup still work as I'm used to, but it
caught my attention pretty much every day which started to get on my nerve.
So I searched for a solution or work-around and came up with this patch
(I'm no programmer though, so this might be a really bad way of 'fixing'
it):

conn = connection.PipeConnection(stdout, stdin, conn_number)
---- END ---
I noticed that the 'subprocess' module is already used for Windows ('if
os.name == "nt"), so I tried to use the same code instead 'os.popen2'. I
had to change 'shell=false' to 'shell=true' to make it work.
I did a couple of test runs and it seems to work, so I'll put it in use
on my systems and keep an eye on them. If anything comes up, I'll report.
Regards, Danilo
