title: list index out of range when performing database queries in Hypothesis function
body: <p>I'm using Python Hypothesis to write random tests for database. 
  After 1-2 loops of insert the given values to the table I get list index out of range and @seed to reproduce. 
  There is nothing that suppose to fail, I'm not asserting anything yet.
  How can I debug this? </p>
  
  <p>Thanks </p>
  
  <pre><code>        run_statement("create table t (x int)")
          @given(st.integers(1,10), st.integers(1,10))
          def insert_select(x):
              assume(x)
              run_statement("insert into t values ({})".format(x))
              select_results = run_statement_with_results("select * from t")
              print select_results
  
          insert_select()

  <pre><code>You can add @seed(257907719204305935240373390472712621009) to this test to reproduce this failure.
