org.eclipse.jgit.errors.MissingObjectException: Missing blob [message #768095]

Hi guys,

i'm creating a UI contribution to Git repositories view that creates a
diff patch for a repository. Pretty much what i want to achieve is the
same as executing "git diff > myPatch.patch".

My code is looking like this:

FileDialog dialog = new FileDialog(part.getSite().getShell(), SWT.SINGLE
| SWT.SAVE);
String fileName = dialog.open();

if (repository != null && fileName != null) {
Git git = new Git(repository);
DiffCommand diffCommand = git.diff();
try
{
List<DiffEntry> diffEntries = diffCommand.call();
FileOutputStream outputStream = new FileOutputStream(new
File(dialog.getFileName()));

DiffFormatter formatter = new DiffFormatter(outputStream);
formatter.setRepository(repository);
formatter.format(diffEntries);
outputStream.flush();
outputStream.close();
}
catch (GitAPIException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
}

However, I always get the same exception when executing
DiffFormatter.format(List<DiffEntry>):

....

Any clue what could be going on?

Cheers!
Víctor.

I forgot to mention that I'm using JGit 1.1.0.201109151100!

Also, I get the same exception with nightly builds (1.2.0).
