[web2py] Too many values to unpack -- regression?

[Brad Miller]

I just upgraded my app to the latest 2.0.3 (stable)  and while checking 
some of my pages got the following error:

Traceback (most recent call last):

    value,tz = value.split('-')
ValueError: too many values to unpack

This is the result of this this query code, which continues to work under 
1.99.7

    count = db.useinfo.id.count()
    last = db.useinfo.timestamp.max()
    res = db(db.useinfo.course_id==course.course_id).select(
        db.useinfo.sid, count, last, groupby=db.useinfo.sid, orderby=count)

I'm assuming this is some kind of regression since the same code is working 
in 1.99.7, but maybe I'm doing something that I could do  but no longer 
should??
