it could be something like the feature's build.properties uses a wildcard (feature.*) instead of listing feature.xml and feature.properties. Tycho doesn't like wildcards in the bin.includes=... directive
could also be an upstream eclipse bug in that your feature declares a plugin which provides its branding, and the BRANDING plugin's manifest.mf fails to define that it's a plugin (bundle-localization, iirc)
or that the plugin's build.properties uses a wildcard instead of listing both plugin.properties, plugin.xml
