The problems seems near Form<<unhibernate and seems related to ByteArray decompression:

unhibernate
    "If my bitmap has been compressed into a ByteArray,
    then expand it now, and return true."

    (bits isMemberOf: ByteArray)
        ifTrue: [bits _ Bitmap decompressFromByteArray: bits. ^ true].
    ^ false
