I'm not sure that you should as you are in danger of forking PyKDE and will 
end up with the KDE blessed version N that behaves differently to the regular 
version N.

As the bug has already been fixed in current versions of SIP, all I can 
suggest is to go through the ChangeLog and see if something rings a bell. 
Also the mailing list archives for something similar to get a date where it 
might have been fixed. If you can narrow it down to a date range I can send 
you diffs.
