Contexts can't be deleted if database tables are prefixed

This bug might be in ctools but I report it here as I experience it in Context. If you try to delete a context through the context UI *and* your database tables has a prefix the context will not be deleted. I've scratched my head over this on my own site for a while, but just confirmed it on a couple of fresh Open Atrium installs now.

If the db is prefixed you get:

user warning: Table 'oabeta8.context' doesn't exist query: DELETE FROM context WHERE name = 'deleteme' in /Applications/MAMP/htdocs/oa/profiles/openatrium/modules/contrib/ctools/includes/export.inc on line 189.

..and the context is not deleted. If the db isn't prefixed the context deletes as expected.
