I am using unstable/experimental, and when

pbuilder create

When it nearly success, an error occoured :

I: mounting /proc filesystem
mount: /proc already mounted or /media/tmpfs/pbuilder/4079/proc busy
mount: according to mtab, /proc is mounted on /proc
W: Aborting with an error
I: cleaning the build env
I: removing directory /media/tmpfs/pbuilder/4079 and its subdirectories
rmdir: failed to remove `/media/tmpfs/pbuilder/4079/proc': Device or
resource busy
rmdir: failed to remove `/media/tmpfs/pbuilder/4079': Directory not empty

And the base.tgz create before, works well.
