Bug#619650: File descriptor 4 (pipe:[556425]) leaked on lvs invocation. Parent PID 17535: /bin/sh

[Jonathan Nieder]

Package: grub-pc
Version: 1.99~rc1-5
Severity: minor
Justification: cosmetic

Hi,

Typical experimental amd64 system.  Some warnings from today's
upgrade.  This might be a duplicate of bug#592834 and bug#549976, but
I'm filing it separately just in case.
