Cannot deserialize instance of date from VALUE_STRING on salesforce

Hello Guys,

        I am working on salesforce from past few days. Just discover the bug related to date field setting using databasedotcom gem. When we are setting date value using ruby 1.9.2 it works as per expectation but with ruby 1.8.7 it gives error like 'Cannot deserialize instance of date from VALUE_STRING value'. To resolve this issue need to install latest gem version databasedotcom-1.2.7.

See this thread on github to get more detail
