Comment 14 for bug 480102

The fix for this bug does not seem to have helped the import of the KARL3 branch

The bug was obscured at first by a new bug, lp:626900, but the patch I added to
fix that bug causes the karl3 import to fail again with the same traceback.

See step 4 in this attachment to lp:626900 for the traceback:
