[Building Sakai] Failed import of IMS QTI formatted file in question pool throws exception

[Doreen Minich]

A prof tried to import an IMS QTI formatted file into the Tests & Quizzes/Question Pool and it failed.  Now they have a nasty bug report following them around Sakai anytime they access a question pool.  How can we clear up the error (seen below)?  I saw a jira regarding failed QTI import files not getting removed and the fix is clearing out /tmp/jsf/upload_tmp/qti_imports/... Is that the only solution and should this directory always be empty?
