[oe] release 2010-12: tar error

[Frans Meulenbroeks]

Not sure if this is reproducible or a race but when building console-image
for minimal for calamari I got:

ERROR: Function staging_packager failed
NOTE: Task failed: ('function staging_packager failed',

Log data follows:

NOTE: package linux-2.6.30-r6: task do_package_stage: Failed

Didn't have time to dig into this. Sry.
