scraperwiki.sqlite.save_var / .get_var wierdness (poorly defined)

[scraperdragon]

import scraperwiki
print scraperwiki.sqlite.get_var('jam')
scraperwiki.sqlite.save_var('bacon',12)
print scraperwiki.sqlite.get_var('bacon')

If run once, correctly gives:

None
12

If run twice, fails with:

Traceback (most recent call last):
  File "test.py", line 3, in <module>
    print scraperwiki.sqlite.get_var('jam')
  File "/usr/local/lib/python2.7/dist-packages/scraperwiki/sqlite.py", line 73, in get_var
    dt.execute(u"CREATE TABLE %s (`value` blob, `type` text, `key` text PRIMARY KEY)" % dt._DumpTruck__vars_table, commit = False)
  File "/usr/local/lib/python2.7/dist-packages/dumptruck/dumptruck.py", line 115, in execute
    self.cursor.execute(sql, *args)
sqlite3.OperationalError: table _dumptruckvars already exists
