Have you found out which Page it tries to deserialize? Did you try to deserialize this exact page using another widget? The exception indicates the internal object stream format is corrupted. So this would indeed mean it would also occur if you try to to deserialize it using a "normal" widget. Here is more info about the (de)serialization protocol http://java.sun.com/j2se/1.5.0/docs/guide/serialization/spec/protocol.html#8101
I could be way of here so please correct me if I am wrong: I don't know the Wicket internals exactly, but I noticed that the DiskPageStore uses a pool of FileChannels to access the files and if I understand the code correctly it allows the file to be opened for read and write the same time. See FilePoonChannel.newFileChannel where the channel is opened in "rw" mode. So maybe it could be a timing issue and you are trying to deserialize a Page that is still in the process of being serialized?
