Could not get tags with allTagsWithError

[Whirlwind]

I have a git repo, and there are some tags in the repo. I use the - [GTRepository allTagsWithError:] could not get any tags.

I debug the code, I found that :

static int GTRepositoryForeachTagCallback(const char *name, git_oid *oid, void *payload) {
	struct GTRepositoryTagEnumerationInfo *info = payload;
	GTTag *tag = (GTTag *)[info->myself lookUpObjectByGitOid:oid objectType:GTObjectTypeTag error:NULL];

	BOOL stop = NO;
	if (tag != nil) {
		info->block(tag, &stop);
	}

	return stop ? GIT_EUSER : 0;
}

The lookUpObjectByGitOid: will return nil.

And debug into it, I found the odb_read_1 in libgit2 will find a oid with type GIT_OBJ_COMMIT, it do not match the GIT_OBJ_TAG, so the type is mismatch.
