[buildd-tools-devel] Bug#571806: sbuild: STDERR not being piped in Sbuild::Build::run_apt

[Andres Mejia]

Package: sbuild
Version: 0.60.0-1
Severity: normal

It looks as though STDERR is not being properly piped in the run_apt()
subroutine. This problem may be in Sbuild::Chroot, but I haven't thouroughly
checked. This is from sbuild version 0.60.0-1 with the patch in bug #403246.

Here's a debug output. Note the 'E: Couldn't find package' message and how
it's missing in $msgs at the end.
