Additional information:

Still not working today - can you guys roll-back the version on beta.codenvy.com until it's fixed???
We have a roll forward policy due to data migrations. It's labeled as a blocker and hot fix investigations are underway.
It seems like this issue is still there in codenvy.io IDE.
