For some reason, Google Translate sets the icon's MIME type to image/* in the web app manifest. Because the manifest parser uses hyperium/mime, which does not allow MIME patterns/ranges by default, the parsing will fail and result in that error.

As a workaround, you can install Google Translate if you uncheck "Use the manifest for determining app properties". I'll check if I can also allow MIME patterns in the parser.
