Please help to complete python-debianbts

I'm currently working on an updated version of python-debianbts a Python interface to Debian's Bugtracker. The goal is to equip the Bugreport class with all available attributes delivered by the SOAP interface. The problem is, that for some attributes it is not quite clear what data they provide and in which datatype they are wrapped. For example the mergedwith attribute should be a list of bugnumbers, but it seems to be a single Integer when merged with one bug and an empty String when the bug is not merged at all. Some attributes have an ambiguous name and it's hard to guess what they mean, for example there is an id and a bug_nr and both seem to contain the same information.

There is a git branch for this task and a wiki page collecting all available information. If you have some experience with SOAP, our BTS and some time to kill, your help would be appreciated.
