Branch command doesn't fetch all branches

[dnaber-de]

Here I have a strange situation where the branch command seems to stumble parsing all branches correctly.

Here's a plain git branch -a result:

$repo = '/path/to/repo';
var_dump( `cd $repo && git branch -a` );
/**

Now this is what PHPGit returns:

$repo = '/path/to/repo';
$git->setRepository( $repo );
$branches = $git->branch( [ 'all' => TRUE ] );
var_dump( array_keys( $branches )  );

I used array_keys() to keep the output short. You can see, it seems to loose master and ignores completely remotes/mirror/master.

Any idea what could be the reason on this?

It points out that the missing branch master has a hash that is 8 characters long. So this in in fact a symptom of #22.
