Error on query initialization - intermittent

      About 1 in ten times, I get the error as shown in the stack trace below. This happens when I run test, or when I start the app. The only way to resolve (when testing) seems to be to blow away the repository.

      It always happens at the point the query manager is accessed (triggering the query subsystem to start up). It DOES NOT cause an exception to be thrown back to the caller, I just noticed it in the logs. Basically the queries return NO data at all (and show up as test failures of course).

      In each case when I startup the system/test, if the repository exists I use it, and (for tests) clean it by deleting the root node of the user content, and then starting again, otherwise there is nothing that exciting.

      Please let me know if more info is needed.
