Comment 19 for bug 304134

Here is a shorter reproduction recipe:

svnadmin create repos
svn co file://`pwd`/repos svn-wc
cd svn-wc/
svn mkdir parent
svn commit -m "Added parent."
svn mkdir peer
svn commit -m "Added peer"
echo "A" > peer/file
svn add peer/file
svn commit -m "Added file"
svn up
echo "B" > peer/file
svn mv peer/ parent/child
svn commit -m "Made peer a child, with mods."
svn up
bzr up # works
cd parent/
svn up
bzr up # crashes
bzr: ERROR: exceptions.KeyError: u'child/file'
