[Building Sakai] T&Q -- multiple choice question always scores zero?

Short version:

One multiple-choice question on a quiz always scores zero. Even with
the right answer chosen. :(

We have a quiz on 2.6.x that's multiple-choice on each question, where
each question gets X points. On one question, the correct answer is
"C" (out of A, B, C, D, E) and it's always scored ZERO (0.0) whether
option C is chosen by the student or not. So nobody is scoring 100% on
this quiz even if they should.

Ideas?



Long version:

I could send screen-snaps if that'd be helpful. What would cause this,
and how to find it / fix it?



Addendum:

As a diagnostic aid, we tried to export/import this quiz but ran into
trouble here as well. This is *not* the main issue, but here goes:

- export as QTI v1.2 (in firefox)
  - tried save-as, got html-wrapper with the XML inside
  - tried view-source then save-as, same problem
  - did view-source, select all, copy and paste into wordpad

- upon import, we see an error box in the web page:
  There was an error importing this assessment. Ensure that the file
is correctly formatted IMS QTI. Error
details:org.sakaiproject.tool.assessment.services.qti.QTIServiceException:
java.lang.NullPointerException

This may be due to cut-and-paste vs. utf-8 encoding.
