In IDBTransactionBackendImpl::taskEventTimerFired: if (!m_pendingEvents && isTaskQueueEmpty()) { // The last task event has completed and the task // queue is empty. Commit the transaction. commit(); return; } This does not account for m_pendingPreemptiveEvents which may nonzero 0 even if there are no events in the queue. For example, after a createIndex() call it might bump that count but yet have placed any tasks in the queues or bumped m_pendingEvents. If the timer fires, the commit() could occur before the indexing occurs. 768696 1 jsbell 2012-11-15 17:02:46 -0800 Landed this fix as a possible patch for webkit.org/b/102283 so marking as a dupe *** This bug has been marked as a duplicate of bug 102283 ***
