Comment 6 for bug 1389321

Phillip and all others: thank you for your incredibly quick response and the fix you provided in no time!

I did test the newly built package util-linux_2.20.1-5.1ubuntu20.3_i386.deb and can confirm: partx from this package gets offset and sizes right with the same loop device where the previous version failed. So this fix works for me, and I will change the status accordingly.
