I agree that that line of the patch looks buggy.

Judging by


and some of the things linked from there, it looks like the former
maintainer of the Debian package for libmng orphaned that package
shortly *before* uploading this fixed version to experimental, and the
package hasn't been touched since.

What's really needed is a new maintainer for that package, but I'm not
sure I can volunteer in that role and expect to be able to hold it up

If it would be accepted, a NMU to update the package to current
standards (and current upstream, if any, which would involve updating
any still-applicable patches) and upload it to unstable would probably
be enough, but I'm not sure that would be considered appropriate in the
absence of anyone to maintain the package.
