I'm having the same problem:

* roundup 0.6.7
* python 2.2.1
* Sun Java Desktop System (based on SuSE 8.1)

Using the demo instance I get the following trackback (including as an 
attachment too):

KeyError: OlzprIFFW5P6ATmJ5vkiZdHC6U95Zgd
Python 2.2.1
/usr/bin/python


A problem occurred while running a Python script. Here is the sequence 
of function calls leading up to the error, with the most recent (innermost) 
call first. The exception attributes are:
      __doc__ = 'Mapping key not found.' 
      __getitem__ = <bound method KeyError.__getitem__ of 
<exceptions.KeyError instance at 0x8434f24>> 
      __init__ = <bound method KeyError.__init__ of 
<exceptions.KeyError instance at 0x8434f24>> 
      __module__ = 'exceptions' 
      __str__ = <bound method KeyError.__str__ of <exceptions.KeyError 
instance at 0x8434f24>> 
      args = ('OlzprIFFW5P6ATmJ5vkiZdHC6U95Zgd',)

As an aside to this, how easy is it to disable the registration confirmation 
entirely? This roundup instance is for internal use so the confirmation 
isn't really needed.
