The compiler team's explanation

Note: this error code is no longer emitted by the compiler.

The plugin attribute was malformed.

Erroneous code example:

#![feature(plugin)]
#![plugin(foo(args))] // error: invalid argument
#![plugin(bar="test")] // error: invalid argument

The #[plugin] attribute should take a single argument: the name of the plugin.

For example, for the plugin foo:

#![feature(plugin)]
#![plugin(foo)] // ok!

See the plugin feature section of the Unstable book for more details.
