This is a bzr issue, not an Emacs one, as can be demonstrated:


mkdir test1
cd test1
touch 1 2
bzr init
bzr add
bzr commit -m "commit1"

cd ../
bzr branch test1 test2

echo change >| test1/2
bzr commit -m "commit2" test1

cd test2
echo other-change >| 2
bzr pull  # -> conflict in file 2

echo change >| 1
bzr commit -m "Try to commit file 1 only" 1

Result:
  bzr: ERROR: Conflicts detected in working tree.  Use "bzr conflicts"
  to list, "bzr resolve FILE" to resolve.
