Thank you for taking the time to report this bug and helping to make Ubuntu better.
It seems clear to me that open-vm-tools in Trusty should Break/Replace open-vm-toolbox (<< 2:0~) [or similar] to resolve this. I've confirmed that the packages in the archive do conflict as your error message described. But I haven't yet managed to reproduce your failure. Doing so would help me verify my understanding and test the solution.
