The stack trace indicates an unexpected state of the query result cache.

We can release a new build with writing relevant information to the log when it happens in order to diagnose the cause.

Further analysis of the stack trace revealed an issue that can cause this exception and was now fixed in build 2.7.6_02.

Thank you for this report.
