I can reproduce this with trunk:

bzr init /tmp/ignore-test
cd /tmp/ignore-test
bzr ignore / # causes traceback

It's probably a shallow bug.

Thanks to a patch from doxxx this is now fixed in lp:bzr. It should be included in the 2.1 release.

Please remember to set the milestone when closing a bug, if its known.
This helps show our progress to folk coming along a little later, or who
are disconnected from the day to day.
