After update form QB 6.0.9 to 6.0.15 we got errors by perforce ceckout
We have one Repository to checkout specified files by Label.
After the update from 6.0.9 to 6.0.15 the cheockout form this repository failed with message below

Failed to run command: p4 -p server:port -u user -P ****** -C winansi -q describe -s LabelName
Command return code: 1
Command error output: Invalid changelist number 'LabelName'.

I think the describe command doesn't work on a label, but it works with Version 6.0.9 ?!
