[Insight-users] Type error in CannyEdgeDetectionImageFilterConnectVTKITK.py

[Gaëtan Lehmann]

Hi,

The "u" is added by the newer versions of cableswig. All the stable  
releases are not using that additional "u".
I suspect you have mixed a build with an "old" cableswig, and a build  
with cableswig cvs. Can you check that you are using the same  
cableswig everywhere?

If you have mixed the cableswig version, a simple clean and rebuild of  
your projects should fix the problem.
