The de-muddled package has a zero byte corrupted icon file.

Here are some steps to replicate.

• In Mudlet, open the Package Exporter.
• Upload your icon image. My example file is 512x512 png called icon.png.
• Export the package, creating a PackageName.mpackge file.
• Run de-muddler -f PackageName.mpackge. This creates a PackageName folder with the extracted package inside.
• Navigate to and attempt to open PackageName/src/resources/.mudlet/Icon/icon.png.
• This file is zero bytes and will not open.

Steps to verify Mudlet's Package Manager exported correctly.

• Manually extract the PackageName.mpackage with 7-Zip.
• Navigate to and attempt to open PackageName/src/resources/.mudlet/Icon/icon.png.
• This file opens correctly and has the correct file size.

There is an issue with de-muddler's extraction of the icon file.
