Description Thomas Ehrnhoefer 2016-03-30 05:18:46 EDT

What steps will reproduce the problem? (at least on my machine)
1. Close history view
2. Open history view
3. Observer error happening and history view remains empty

The same error appears when using the "Show In...History" action.

This might be the same as https://bugs.eclipse.org/bugs/show_bug.cgi?id=488719, but I am unsure
