Do you know what level you updated from? That's always handy to know when
trying to pinpoint when a problem was introduced.

So it's got something to do with validation. Do you know if it worked at
all after validation of ModelAdmin was added (r7929) and has broken
subsequently, or if it broke as soon as ModelAdmin validation was added?

Determining which part of the fieldsets definition generates the error would
be helpful. You might be able to determine it by looking at the local vars
in the debug page. Alternatively you could experiment with removing pieces
of it to see which field is causing the error. Basic fieldsets validation
works (I'm sure it's got tests and I have models that use it and still work
on current newforms-admin), so it's something specific to your model. If
you could strip your models down to a reasonably simple testcase that
displays the error it would be helpful.
