Hi!
To help resolving interwiki conflicts, I programmed a feature to output interwiki graphs. It's still under development, but works fine already.
You need pydot to use it, which is freely available here: http://dkbza.org/pydot.html
If you then set interwiki_graph = True in your user-config.py, interwiki.py will output graphics like these if it encounters conflicts:
http://meta.wikimedia.org/wiki/Image:Angora.png http://meta.wikimedia.org/wiki/Image:Antarktischer_Krill.png
Colours:
White - normal page Grey - disambiguation page Yellow - redirect Red - non-existing page Blue - Link within the same wiki
The second graph is quite chaotic, but if you look carefully you will find hints which might help you resolving the conflict.
Have fun
Daniel
