I am trying to move freeplane's repository (GPL-project) from bzr to
git, but when I do this:

$ mkdir freeplane-git1
$ cd freeplane-git1
$ git init .
$ bzr fast-export --export-marks=../marks.bzr ../trunk/ | git fast-import --export-marks=../marks.git
$ git checkout

then there are no errors, but the resulting working index is broken:
 freeplane-git1/freeplane_plugin_formula/src/org/freeplane/plugin/formula
 contains SpreadSheetUtils.java which belongs to package
 'org.freeplane.plugin.spreadsheet' and which is no longer in the bzr
 trunk that I imported!

If you run only the bzr half of your command and inspect the output, you
will see that the file in question is mentioned twice.  Once in a commit
on "refs/heads/master" that renames into it from another file:

  R freeplane_plugin_spreadsheet/src/org/freeplane/plugin/spreadsheet/SpreadSheetUtils.java
    freeplane_plugin_formula/src/org/freeplane/plugin/formula/SpreadSheetUtils.java

That same revision also removes it, but is uses the original name for
the deletion (the bzr revision actually renames the containing
directory).  That's probably what confuses git fast-import.

Here is a test case:

bzr init
mkdir a
bzr add a
touch a/b
bzr add a/b
bzr ci -m a
bzr mv a b
bzr rm b/b
bzr ci -m b
bzr fast-export .

The output contains these lines:

R a/b b/b
D a/b

Changing the second line to D b/b fixes the bug.
