WAKomEncoded fails serving CSS files from WAExternalFileLibrary

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Create a File Directory Request Handler pointing to a directory containing a 
css file.

2. In a WAComponent application, in the updateRoot method, reference the css 
file, e.g.

    anHtmlRoot stylesheet url: 'css/myfile.css'. 

3. Open the application, observe that the css file is not returned.

What is the expected output? What do you see instead?

Expect the css file contents, receive instead

    Internal Error: ByteArray>>isByteString


What version of the product are you using? On what operating system?

Seaside 3.0, Pharo 1.1,11411, Ubuntu Linux 9.10


Please provide any additional information below.

The error appears to be coming from this method: 

    GRPharoUtf8CodecStream>>nextPutAll: aString

    aString isByteString
        ifTrue: [ self encodeFast: aString ]
        ifFalse: [ self encodeDefault: aString ]

which would explain why it does not occur in the unencoded WAKom.
