Internal server error on rest get tags call... & changesets call

When trying a get on the url for our project alpha_developer/alpha_services

https://bitbucket.org/api/1.0/repositories/alpha_developer/alpha_services/tags/?start=1a58b16f53368a80a9126abd921270a6c7bcdf8a&limit=40

We get the returned json exception (this happens with any sha)
