[PATCH] Avoid infinite recursion in KCC

[Clive Ferreira]

Hi,

Included in these patches are a fix by Douglas Bagnall to correct a mix
up made between a str and an object which caused infinite recursion and
a method call on a None type.

I added a test patch which uses a database dump file which originally
triggered this edge case. This database consists of 5 unconnected DCs,
and the bug is triggered by code to create additional edges which
normally never ran. In normal cases, the leftover connections made
during a join would prevent these additional edges from being created.

cheers


Clive
