memcached crashed in Configuration::getCouchBucket

I see crash from http://qa.hq.northscale.net/job/CouchbaseServer-SanityTest-4Node-
Centos64/63/consoleFull run on build 2.0.2-795-rel

seems it's the test:
./testrunner -i fournode.ini -t viewquerytests.ViewQueryTests.test_employee_dataset_all_queries,limit=1000,docs-per-day=2,wait_persistence=true

but this job doesn't generate collect info after failures, and I have logs that have been obtained much later
