[Building Sakai] Samigo NPE error

[Kirschner, Beth]

We have a user who's unable to access her Samigo Question Pools, after attempting to import an invalid xml file:
	https://jira.sakaiproject.org/browse/SAM-2234

Can anyone suggest some SQL that might 'clean up' the problem as a workaround such that she could continue using Test & Quizzes? Right now she gets a NPE crash every time she tries to access the Question Pools.

Thanks,
- Beth
