Bug#741227: pbuilder fails with unmet build dependencies

[Larry Lee]

Package: pbuilder
Version: 0.213ubuntu1

  I rebuild packages with pbuilder,things work fine in most cases.But when
there is an empty line before "Source"  field in control file, getting
build-depends list from control will return null.for example:libnotify4.

Package: pbuilder-satisfydepends-dummy
Version: 0.invalid.0
Architecture: amd64
Maintainer: Debian Pbuilder Team <pbuilder-maint at lists.alioth.debian.org>
Description: Dummy package to satisfy dependencies with aptitude - created
by pbuilder
 This package was created automatically by pbuilder to satisfy the
 build-dependencies of the package being currently built.
dpkg-deb: building package `pbuilder-satisfydepends-dummy' in
`/tmp/satisfydepends-aptitude/pbuilder-satisfydepends-dummy.deb'.
"
As we can see ,there is no Build-Depends in pbuilder-satisfydepends-dummy's
control file.
I read the code about getting dependencies from control, see sed stop
reading input lines from control file when matching empty line"/^$/q",then
I add one line to delete the empty line,if any, before Source field. After
this, pbuilder goes well.
