If I understand it correctly, this is what you get directly in the
luci interface.  As you can see, the traceback is not complete, but
it may get trimmed somewhere on the way from source to the web browser
(side question: is the snippet you provided really complete, i.e.,
not followed by the rest of expected traceback?).

Anyway, authoritative source to check for details about the problems
in luci is its log file located at /var/log/luci/luci.log by default.
Could you please watch this file while reproducing the issue (best
by issuing "tail -f /var/log/luci/luci.log" in a separete terminal)
and provide the respective part of the log?  This might help a lot.


If you are only managing a single cluster or so in luci, perhaps
I would recommend you to drop existing luci-internal database and
start all over:

    service luci stop
    rm -i /var/lib/luci/data/luci.db
    service luci start


Hope this helps.
